[TextArea]
TextArea is Gideros library to show and edit multiline and oneline texts.
TextArea supports hardware and virtual (built-in) keyboard input. Text can
be scrolled via mouse/touch and selected via mouse or virtual keyboard.
All standard text operations are supported: Select All, Duplicate, Cut, Copy,
Paste, Undo, Redo. If text can't fit into width and height vertical and
horizontal sliders will appear to help with the navigation. Each text can
have it's own colors and alphas of text, sliders, selection and cursor.
Various alignment modes are available: left, right, center and justified
with ability to suppress word breaks ('wholewords' setting). When text
editing is finished TextArea will run callback if defined.
[Virtual keyboard]
Virtual keyboard is fully customizable from within itself: you can set
each color, change font and sound, modify height, set cursor delays etc.
More than 150 layouts is available for it in included keyboard layouts file
(kblayouts.lua). Keyboard settings are automatically saved in a file
('keyboard.json' by default). It also automatically resizes when screen
resolution changes and fits editable text. If you need to popup it without
touch, for example for cursor settings, you can press "Menu" key on hardware
keyboard.

[Keyboard Layouts]
Can be set via TextArea.setKeyboardLayouts(layouts).
All layouts are grouped into languages:
{lang1 = {...}, lang2 = {...}, ...}
Each language group can contain up to 8 main layouts at 1..8 indexes:
{l1, l2, l3, l4, l5, l6, l7, l8}
1: lowercase letters (shift: off, alt: off)
2: uppercase letters (shift: on, alt: off)
3: main symbols (shift: off, alt: on)
4: extra symbols (shift: on, alt: on)
5: bottom bar
6: colors menu
7: options menu
8: cursor menu
Each missing layout will be loaded from default layouts.
Each language group also supports extra layouts. Extra layout is an layout
