NOTES-1.1

--- 1.1.16 ---------------------------------------------------------------------
- Wings now compiles cleanly on FreeBSD. [scorpius]

- For developers: Erlang/OTP R13B02 is now required for building
  Wings. [bjorng]

- When importing holes were not always handled correctly.
  There could be faces marked as holes internally, but the faces
  would still be visible. Future operations (such as Combine), could
  then cause the faces to suddenly disappear (i.e. become holes).
  (Thanks to Siber.) [bjorng]

- Wings will now validate holes when loading .wings files,
  and remove from the list of holes any non-existent face or
  face that is not invisible. (Importing objects with holes and
  saving in a previous release of Wings could cause such
  inconsistencies, as described in the previous release note.)
  [bjorng]

- Selecting many elements in many objects using marquee
  selection is now much faster. (Thanks to ycarry for noticing
  the slowness.) [bjorng]

- The Separate command is now significantly faster when run
  on objects with many sub-objects. (Thanks to ycarry for noticing
  the slowness.) [bjorng]

- Opening .wings files without vertex attributes is now
  slightly faster. (Thanks to ycarry.) [bjorng]

- Added Bbox Move and Scale to Selection tools. BBox now
  displays with a visible center and uses the user define Vector
  colour. [optigon]

- Added colour prefs for the Menubar and Info Line Text. [optigon]

--- 1.1.15 ---------------------------------------------------------------------
- It was not possible to load JPEG, PNG, or GIF images (either
  as textures or using the Image Plane commands) on Snow Leopard.
  (Thanks to Riolan and nobrandname.) [bjorng]

- The Tools|Virtual Mirror|Create command will now
  automatically flatten the virtual mirror face. [bjorng]

- The Select|Edge Loop|Edge Loop To Region command will
  now allow virtual mirror and hole edges to close an edge loop.
  (Suggested by FonteBoa.) [bjorng]

- Combine and Separate became much slower in 1.1 if there
  were many objects in the scene. This has been corrected.
  (Thanks to ycarry.) [dgud/bjorng]

- Select by material is now much faster for big objects with
  more than one material. (Thanks for ycarry for noticing the
  slowness.) [bjorng]

- Gordo has designed new (much nicer) install and uninstall icons
  for the installer on Windows. [bjorng]

- Undoing a change of UV coordindates would not update the
  AutoUV window. (Thanks to no204.) [bjorng]

- Creating a new Geometry window and moving the mouse cursor
  over the toolbar of the new window before doing anything else would
  cause Wings to crash. (Thanks to BlackHarmo.) [bjorng]

- Area lights can now be selected from both sides, not only
  from the front face. (Thanks to Micheus.) [bjorng]

- Newer LWO files may contain a sub form of POLS called SUBD.
  Unfortunately, I have found no description on how to interpret those
  forms. If you happen to know how to interpret those forms, please
  post a message in the Programming forum. The LWO importer will now
  quit with an error message instead of crashing when encountering
  ae SUBD form. (Thanks to Siber.) [bjorng]

- Fixes to Sweep. (Thanks to BlackHarmo and Fonte Boa). [optigon]

- Windows could appear above the visible screen area. Now some code
  checks for this as windows are loaded and moves them within the visible
  range. [optigon]

--- 1.1.14 ---------------------------------------------------------------------
- If View|Scene Lights has been turned on, but the scene
  contains no lights, the usual modeling lights will be turned on
  instead so the objects do not turn black. [bjorng]

- Undoing Absolute Command|Snap would undo the preceding
  command too. (Thanks to BlackHarmo.) [bjorng]

- In vertex selection mode, unselected vertices would not be
  shown if there were any hidden faces or holes. [bjorng]

- Some inconsistencies noticed by gordo in the user-interface
  have been corrected. [bjorng]

- New Feature: Collada export. Objects including
  UV coordinates and materials are exported. Lights and
  cameras are not exported yet. [metadave]

--- 1.1.13 ---------------------------------------------------------------------
- Selecting two objects, one with a virtual mirror and one
  without a virtual mirror, and Tweaking the object with the virtual
  mirror would cause a crash. (Thanks to BlackHarmo.)
  
  For developers: wings_pick:do_pick/3 and wpa:pick/3 returns more
  information about what was picked in the second element of the
  result tuple. Plug-ins that use the second element must
  be updated. [bjorng]

- Select|Edge Loop|Edge Loop (and Grow/Shrink Edge Loop) can
  now select edge loops around holes. [bjorng]

- This release for Mac OS X has been built with Snow
  Leopard (10.6) as the host OS. It is still supposed to work on
  Tiger (10.4) with either PPC or Intel CPUs, but I have no way to
  actually test that. [bjorng]

- On Windows, the wings_crash.dump file will now be written to the
  Desktop, since writing it to the installation directory for Wings
  would not work in Windows Vista or Windows 7. [bjorng]

- Vertex colors that were completely white were not saved in
  .wings files. (Thanks to tuxtax.) [bjorng]

- The '+' and '-' keys on the keypad can now be used for
  adjusting the magnet radius in Tweak mode. [bjorng]

--- 1.1.12 ---------------------------------------------------------------------
- For developers: In the source distribution, there is a new
  text file CodingGuidelines containing coding guidelinings for
  Erlang programming in general and Wings programming in particular.
  (Thanks to optigon, deerwood, and scorpius for comments on the
  first draft.) [bjorng]

- For developers: Basic multiple column support has been
  implemented in the table widget in wings_ask. [bjorng]

- Doing a vertex bevel on an object with both vertex attributes
  and a virtual mirror would cause a crash. (Thanks to ycarry.) [bjorng]

- Exporting objects with holes and more than one material
  would cause a crash. (Thanks to ycarry and TulipVorlax.) [bjorng]

- Exporting a scene with area lights with the Yafray exporter
  would cause a crash. (Thanks to spacemanspiff7.) [bjorng]

--- 1.1.11 ---------------------------------------------------------------------
- Clicking the Cancel button in the file dialog for Mac OS X
  would cause a hard crash. (Thanks to ycarry.) [bjorng]

- Wings have had the _hole_ material for a long time to fake
  holes by marking faces that should not be included when exporting.
  
  This release introduce the command Face|Hole to create a holes
  that looks like holes also in the Geometry window.
  
  To remove a hole, select a face adjacent to the hole and RMB
  click on the Face|Hole command to create a face to cover the
  hole.
  
  When loading old .wings files, all faces containing the _hole_
  material will be converted to the new type of hole.
  
  If you load a .wings file saved with this version of Wings in
  an old release, the holes will become hidden faces, but they
  will NOT have the _hole_ material (i.e. they will not behave
  as holes when exported). [bjorng]

- The Turn Edge command will now only turn edges that have
  visible faces on both sides. In previous releases, it would happily
  turn edges next to invisible faces (even edges making up the
  virtual mirror face). [bjorng]

- Face|Extrude (on regions) could be slow if many faces were
  selected in a pattern with many inner corners (e.g. the selection
  obtained by first selecting a single face and then pressing
  "F" repeatedly). [bjorng]

- Palette window: Fixed crash and made the scan command aware
  of the selection mode. (Thanks to Fonteboa and Deerwood.) [dgud]

- Added an edge filter. Original idea and code from Ed Kolis. [dgud]

- Yafray exporter:
  * Changed default settings for Photon Spotlight.
  
  * Added to Help info.
  
  * Changed type for HDRI from HDRI to Image.
  
  * Added .EXR to HDRI Background file browser.
  
  * Added Prefilter option for Ambient light background. [oort]

--- 1.1.10 ---------------------------------------------------------------------
- Tools|Snap Image was broken in several ways. It will now
  also preserve vertex colors. (Thanks to PuzzledPaul.) [bjorng]

- Attempting to extrude an edge between two isolated vertices
  would cause a crash. [bjorng]

- Extrude in edge mode would distort UV coordinates and
  vertex colors. That has been corrected. [bjorng]

- When the hemispherical shader was active, vertex colors was
  shown even for materials that disabled vertex colors, provided
  that the object had at least one material with vertex colors
  enabled. [bjorng]

- Wings 1.1.9 (and 1.1.9.1) would crash when attempting to open
  a .wings file containing area lights saved by a previous version of
  Wings. This has been corrected.  Furthermore, when saving area
  lights, they will be saved in the same way as in versions before
  1.1.9. That means that a .wings file containing area lights saved
  by this version of Wings cannot be opened by 1.1.9.x, but it can
  be opened by older versions such as 1.0.1 and 1.1.8.
  (Thanks to Micheus.) [bjorng]

- Autouv: Fixed Face|Project Unfold crash when every face in
  the chart was selected. [dgud]

--- 1.1.9.1 --------------------------------------------------------------------
- File dialogs would crash on Linux in the 1.1.9
  release. [bjorn]

--- 1.1.9 ----------------------------------------------------------------------
- Calculations of smoothing groups in the Wavefront exporter
  could crash if there was two different edges between the same pair
  of vertices. (Thanks to Siber for reporting this bug.)
  
  For plugin developers: A new field, sg, containing an integer
  representing the smoothing group has been added to the #e3d_face{}
  record. Plug-ins using that record must be re-compiled. [bjorng]

- In the Smoothed Preview mode, changes to vertex colors or
  UV coordinates would not be visible. (Thanks to FonteBoa.) [bjorng]

- Fixed the bugs in the View|Show Colors and View|Show Materials
  reported by Micheus. Also made sure that a change to the vertex
  color option of a material would immediately be seen in the
  scene. [bjorng]

- Repeat cmds for Extrude now fixed. (Thanks to Fonte Boa). [optigon]

- Bevel for vertices now properly updates UV coordinates and
  vertex colors dynamically during dragging. (In the Smoothed Preview
  mode, the UV coordinates will only become correct when the drag
  has finished.) [bjorng]

- If the workaround against disappearing text was enabled,
  there would be crash when attempting to display any character
  not included in the fonts, which could happen when using the
  file dialog on Linux to browse a file system where the filenames
  are encoded using UTF-8. (Thanks to mifth.) [bjorng]

- In the file dialog on Mac OS X, selecting a filename
  containing non-US ASCII characters (such as the Swedish
  letters Å, Ä, or Ö) would cause a hard crash. [bjorng]

- By default, the file dialog box for Linux now assumes
  that filenames are encoded in UTF-8. There is a new checkbox
  to revert to the previous behaviour (that is, to assume that
  filenames are encoded in ISO latin1). [bjorng]

--- 1.1.8 ----------------------------------------------------------------------
- Switching to the Smoothed Preview mode would cause a crash
  if there were any area lights in the scene. (Thanks to Micheus.)
  [bjorng]

- For plug-in developers: The new function wpa:version/0
  returns the version string for Wings. [bjorng]

- Edit|Repeat (Ctrl+D) was broken since 1.1.3. Either it did nothing
  at all or caused a crashed. (Thanks to optigon and deerwood.) [bjorng]

- Magnet Mask|Select bugs fixed. (Thanks to GetaVe and Fonte Boa). [optigon]

- Using one of the commands Show Colors, Show Materials, or
  Show Textures in the View|Show sub-menu, the scene would not be
  immediately updated to reflect the change. Furthermore, if
  Show Colors was turned off and there was an object with vertex
  colors in the scene, there would be a crash. [bjorng]

- AutoUV used to hold a copy of the scene to be able to
  generate a texture with vertex colors or materials.
  
  This extra scene copy has been eliminated. When doing the initial
  UV mapping of an object without previous UV coordinates, the
  materials on the object will be converted to vertex colors (this
  will only be done if there are no previous vertex colors in the
  object AND if the object has non-default materials). The vertex
  colors in the object can later be used to generate a texture.
  
  With this change, vertex colors generated by the Ambient Occlusion
  command can now be baked into a texture. [bjorng]

- If the material 'default' in a .wings file does not have exactly
  the same properties as the 'default' material in Wings, the material
  itself would be renamed to something else (typically 'default2'),
  but the material for the faces that used the material would NOT
  be assigned the new name. [bjorng]

- The object mode (vertex color/material) for objects has
  been eliminated.
  
  Instead materials have a Vertex Colors setting that can be
  "Ignore" (don't use vertex colors; default for new materials),
  "Set" (to use vertex colors instead of the colors in the material),
  and "Multiply" (to multiply vertex colors with the diffuse texture).
  
  The material "default" has "Set" as the value for the "Vertex Colors"
  property, meaning that if you assign vertex colors to face having
  the "default" material, the vertex colors will be visible.
  
  There is a new command (with a sub-menu) in the body mode menu called
  "Vertex Attributes".
  
  When opening a .wings file written by Wings 1.1.7 or earlier, the
  object modes for the objects in the file will be ignored. If there
  are vertex colors, they will be visible on faces that have
  the 'default' material assigned. For faces with other materials,
  the colors or textures in the material will be shown (even if
  the object was in vertex color mode).
  
  When saving a .wings file in this version of Wings and opening
  it in an older version of Wings, all objects will be in
  material mode (even if they have vertex colors).
  
  For plug-in writers: #we.mode has been removed. It also means that
  plug-ins that use #we{} needs to be re-compiled. [bjorng]

--- 1.1.7 ----------------------------------------------------------------------
- In rare circumstances, the progress bar could reach 1.0
  (the far end) even if the operation was not finished and cause
  Wings to crash hard. (Thanks to deerwood.) [bjorng]

- The smooth proxy is now updated directly when invoking
  interactive commands. [dgud]

- New Feature: Create Bounding Box added to the primitives menu. [optigon]

- Scale to Bounding Box selections now keep their original centre. [optigon]

- Turn Edge now preserves Hard Edges. (Thanks to BlackHarmo). [optigon]

- New Feature: Select|Edge Loop|To Complete Loops turns any selection
  into an edge loop selection. Works from all selection modes and is based on
  the request by deerwood to be able to extend loops beyond where they stop
  when using the regular Edge Loop command (L). [optigon]

- Dissolve and Collapse cmds now delete wholly selected efficiently. [optigon]

- Shared vertices are now eliminated on import. (The
  modeling commands in Wings does not allow creating of shared
  vertices (also called waists), i.e. faces that only share vertices
  but no edges, so it should not be allowed on import.) [bjorng]

- When displaying objects that have a virtual mirror face in
  the smooth preview mode (i.e. turning off workmode by pressing TAB),
  the seam between the real part of the object and mirror image will
  now be soft. The Smooth command (and the Smooth Proxy mode) will
  still sub-divide faces around the virtual mirror face as if the
  edges were hard, so Smoothing before freezing the mirror and
  after freezing may still not give exactly the same result
  (how close the result is depends on the object; for some objects
  the difference may not be noticeable). [bjorng]

- New Feature: Magnet Mask Deselect - Subtracts locked elements from
  the current selection. (Thanks to Fonte Boa) [metadave, optigon]
  
  Magnet Mask Select - fixed: Adds locked elements to current selection.
  (Thanks to Fonte Boa). [optigon]

--- 1.1.6 ----------------------------------------------------------------------
- Re-exporting an imported model with tesselation could
  cause a crash. Also, when importing objects that had UV coordinates
  on some faces but not all, UV coordinates would be discarded
  on both side of edges that only had UV coordinates on one side.
  (Thanks to Siber.) [bjorng]

- Separating, then Combining an object with vertex
  attributes would cause a crash. (Thanks to zdarby.) [bjorng]

- Smoothing objects with hidden faces would crash. [bjorng]

- The command Select By|Id would crash in body mode. [bjorng]

- Eliminate selection glitches where elements behind a face
  could be selected through the face. (Thanks to deerwood.) [bjorng]

- Wings would freeze if there were empty objects in the
  scene. (Empty objects can only be created by import or possibly
  by a plug-in, as the core Wings commands will delete an object
  that becomes empty.) [bjorng]

- The Ambient Occlusion plugin will now correctly
  ignore hidden or locked objects. [scorpius]

- Some fixes and improvements to Edge|Circularise. Open edge loops
  should process more uniformly. (Thanks to puzzledpaul). [optigon]

- Warp mouse to proper position follow drag in Tweak. [optigon]

- Toggling xyz constraints in tweak wouldn't update the info line.
  Now fixed. [optigon]

- Tweak Slide would not work correctly for single edges and
  would not work at all for selections of two unconnected vertices.
  Now fixed. (Thanks to Fonte Boa.) [optigon]

- Tweak Slide would not stop at edges. Also made some
  optimisations. [optigon]

--- 1.1.5 ----------------------------------------------------------------------
- Fixed Tweak drag Normal. (Thanks to Fonte Boa). [optigon]

- Moving or duplicating a light in body mode would cause
  a crash on the next attempt to select anything.
  (Thanks to extrudeface.) [bjorng]

- Marquee selection would selected locked vertices or edges.
  (Thanks to ycarry.) [bjorng]

- Select|Similar is now faster if the initial selection
  contains elements that are similar to each other.
  (Thanks to Ran13.) [bjorng]

- The Wavefront (OBJ) exporter now tries to minimize
  the number of smoothing groups. (Thanks to Ran13.) [bjorng]

- Fixed loading models when in smooth-preview mode.
  Reported by Ran13. [dgud]

- There is a major internal change in how vertex attributes
  (i.e. vertex colors and UV coordinates that are associated with
  a vertex in a particular face) are handled.
  
  Vertex attributes used to be stored in the edge table (with
  two words per edge always reserved for vertex attributes)
  and each vertex could have EITHER a vertex color or
  UV coordinates.
  
  Vertex attributes are now stored by themeselves. Objects
  without vertex attributes will consume less memory (two
  words per edge less than in previous releases). Each
  vertex can now have both a vertex color and UV coordinates.
  
  The wings file format should be completely compatible. If
  you load a wings file containing an object with both vertex
  colors and UV coordinates into an older release of Wings,
  only the UV coordinates will be kept. (If you resave such
  a file from an older version of Wings, the vertex colors
  will be permanently lost.)
  
  Most commands have not been updated yet to take full
  advantage of the new vertex attribute implementation. So
  while Ambient Occlusion will preserve existing UV coordinates,
  there is no way yet to show vertex colors at the same time
  as textures.
  
  You can use the commands "Material Mode" and "Vertex Color Mode" in
  the body mode menu to switch between seeing materials/textures and
  vertex colors. (The commands are not new, but there were few
  situations in which they were needed in previous releases of Wings.)
  In a future release, we will probably eliminate those commands and
  extend materials so that you can choose whether vertex colors,
  materials/textures, or a mixture of both should be shown.
  
  Performance seems to be about the same if there are no
  vertex attributes, but somewhat slower for models with
  vertex attributes.
  
  For developers: Plug-ins using #edge.a and #edge.b will not
  compile. Instead use the new wings_va module that provides an API
  to the vertex attributes. I have tried to comment each
  exported function in the API. [bjorng]

--- 1.1.4.1 --------------------------------------------------------------------
- Having wireframe on and workmode off would cause a
  crash. (Thanks to Siber.) [bjorng]

- Select By|Vertices With could select hidden vertices
  (i.e. vertices surrounded only by hidden faces). Similarly,
  Select By|Random could select hidden edges or vertices,
  and Select By|Short Edges and Select By|Sharp Edges could
  select hidden edges. [bjorng]

- The Wavefront (OBJ) exporter will now export smoothing
  groups based on the hard edges in the model. [bjorng]

- For developers: There is a new module wings_va
  which is ultimately meant to encapsulate the details
  of how vertex attributes (i.e. vertex colors and UV
  coordinates) are stored. In this release, wings_va has
  an API mostly for retrieving vertex attributes (i.e.
  it does not yet handle updating of vertex attributes).
  In particular, all functions in wings_face that could
  retrieve vertex attributes (such as vinfo_ccw/2 and
  fold_vinfo/4) have been removed. [bjorng]

--- 1.1.4 ----------------------------------------------------------------------
- For developers: Release notes to be included in a release
  should no longer be directly added to NOTES-1.1 files, but
  instead be written into the check-in comment. Everything in
  a comment from "NOTE:" (without the quotations marks) at
  the beginning of a line to the end of the check-in comment,
  will be included in the release notes.
  
  To extract the release notes, run the script tools/extract_notes.
  It will extract and print all notes for all commits after
  the tag for the latest release. [bjorng]

- The Edge Ring command (Select|Edge Loop|Edge Ring) would
  select edges between hidden faces. [bjorng]

- Selection (finding out which face is under the mouse
  cursor) used to be done using a special selection render
  mode in OpenGL. However, this mode does not work well
  in all OpenGL drivers. Therefore I have implemented my
  own code for selection handling in C as a driver for the
  Erlang emulator. (Thanks to FonteBoa for testing.) [bjorng]

- The proxy mode has been optimized by using vertex arrays. [dgud]

--- 1.1.3 --------------------------------------------------------------------
- Torsten Manz updated the German translation. [bjorng]

- Menu Cleanup: Consolidated Extrude with Extrude Region and Extract Region with
  Extract Faces. Since there is now only one heading each for Extrude and
  Extract, the mouse buttons that activate specific commands have been changed.
  Please see the related info lines for details. [optigon]

- Crash when using Shift Spherical (mmb option) now fixed.
  (Thanks to Fonte Boa.) [optigon]

- Edge|Collapse now deletes edges more uniformly than the previous
  implementation. Also, a Rmb option has been added to automatically cleanup
  any newly created isolated vertices resulting from the collapse edges.
  (Thanks to deerwood and Fonte Boa). [optigon]

- On OpenGL implementations without support for multisampling,
  there would be (harmless) error messages written to the console
  Develop|OpenGL Errors had been turned on. Changed to only
  attempt to use multisampling if the OpenGL implementation supports
  it, and no longer showing the checkbox in the preferences for
  turning on/off multisampling if the OpenGL implementation does
  not support it. [bjorng]

- If a command executed through a hotkey causes an error,
  a dialog box with some help will be shown. [bjorng]

- Major rewrite of how geometry data is sent to OpenGL. We used
  to have a specially written driver, but for future compatibility
  we cannot use a driver. Instead we use vertex arrays.

  This is the first step in this direction and we expect to do
  further optimizations. For the moment, some display updates
  can be slower and some can be faster than before.

  As part of this change, the OpenGL renderer has been removed.
  Sorry for any inconvenience, but it had to go. [dgud & bjorng]

- This release uses R13B01. A bug fix in the array module in R13B01
  eliminates a crash that occurred when all edges in an object
  were dissolved. [bjorng]

- This development release also includes all bug fixes in the 1.0.1 release.

--- 1.1.2 --------------------------------------------------------------------
- Select Similar Normals with the option Connected Faces Only and
  a selection comprising multiple objects would cause a crash.
  (Thanks to pauljs75.) [bjorng]

- Using the Slide command with Clean (Ctrl+Alt+L) would crash.
  (Thanks to gordo.) [bjorng]

- AutoUV: Doing ReMap UV and choosing Strech Optimization would
  cause a crash. (Thanks to betelguese.) [bjorng]

- When creating a texture from vertex colors in the AutoUV window, the
  colors will be properly interpolated (smoothed). [scorpius]

- Keyboard events in Tweak while dragging could cause slow downs. Now Fixed.
  (Thanks to Fonte Boa.) [optigon]

- Additional Geometry Windows can now be closed from within Tweak mode.
  (Thanks to Fonte Boa.) [optigon]

- Dragging in Tweak is no longer limited to the size of the current window.
  [optigon]

- Conflicts due to mouse events in adjacent Geometry Windows have been solved by
  locking the focus to the original window during paint selection and dragging
  in Tweak Mode. (Thanks to Fonte Boa.) [optigon]

- New Tweak option to set Tweak Magnet Increment. [optigon]

- Spherical UV mapping corrected. [dgud]

- There are two new commands in the optional Develop menu:

  * Develop|OpenGL Errors to check for and display OpenGL errors after
    each command.
  * Develop|Print Scene Size to print the scene size.

  Also, the existing commands Time Commands and Undo Stat now handle
  plug-in commands properly.

  The command Tools|Memory Info has been removed. [bjorng]

- New in Tools menu: Ambient-Occlusion Generator/Baker. It works on a per-
  vertex basis and uses a standard inside-out approach. Mesh subdivision
  yields more accuracy. The results are stored in the vertex-colors and can
  also be baked to a texture through AutoUV. [scorpius]

- Extended Shift plugin to work in all selection modes. [optigon]

- New Plugin: Extract Faces. Like Extract Region but extracts individual faces.
  [optigon]

--- 1.1.1 -------------------------------------------------------------------
- The data structure for the vertex tables has been changed.
  (There is one vertex table to keep track of the vertex positions,
  and another vertex table used for finding edges and face around
  the vertex.) The new data structure is faster and uses less memory.
  [bjorng]

- When displaying vertices and edges, a feature in OpenGL called vertex
  arrays is used to faster transfer the data from Wings into OpenGL.
  This way of displaying geometry is slightly faster than the previous
  method. [dgud, bjorng]

- ESDL updated to 1.0.1. (The next release in the 1.1 series will probably
  not work without that version of ESDL.) [bjorng]

- Magnets are now drawn correctly in Tweak when selections across multiple
  objects are dragged. [optigon]

- Selectings multiple objects in Tweak and calling a command via a hotkey would
  only affect one of the objects. Now corrected. [optigon]

- Crash reported by Fonte Boa corrected. [optigon]

- Tweak mode temporary selection fix. [optigon]

--- 1.1 ---------------------------------------------------------------------
- Added a new preference in the Misc tab to turn on a Develop menu
  containing various tools for the Wings developers. [bjorng]

- Added a command to the new Develop menu to automatically time
  all executed commands. The command name and time will be printed
  to the console. [bjorng]

- Added a command to the new Develop menu to automatically print
  out information about the undo queue. [bjorng]

- The data structure for the edge table has been changed. The new
  data structure is faster and uses less memory. Approximately 4
  words (1 word = 4 bytes) per edge is saved.

  Plug-ins that depend on the edge table being a gb_tree will not
  work. More details can be found in the Change log (which follows
  these notes at Sourceforge). [bjorng, optigon]

-----------------------------------------------------------------------------
