Text alignment bug

[baxelrod-bdai]

There is a slight bug related to text alignment. MIDDLE is actually defined twice which prevents you from achieving some alignments. So i suggest this change. It fixes the bug, and also makes these defines more understandable.

#---text flags
#horizontal
H_LEFT        = 0
H_CENTER      = 1
H_RIGHT       = 2
H_ALIGNED     = 3 #if vertical alignment = 0
H_MIDDLE      = 4 #if vertical alignment = 0
H_FIT         = 5 #if vertical alignment = 0
#vertical
V_BASELINE    = 0
V_BOTTOM      = 1
V_MIDDLE      = 2
V_TOP         = 3
