[Bf-committers] How & When could we support right-to-left languages?

[Ton Roosendaal]

Hi,

Here's UI drawing with negated matrix:
http://www.blender.org/bf/blah.png

source/blender/editors/interface.c, uiDrawBlock(), swap first two args  
in wmOrtho2().

Unfortunately a lot of other issues happen still... previews, icons,  
histograms and so on. All pixeldrawing goes L->R...
