Re: [PyOpenGL-Users] Rectangle textures on Mac OS X

[Daniel H. <da...@bo...>]

Hi Mike,

Firstly - thanks for jumping all the way to doing this.

Looks like the extension has made it thro ARB approval.  I found the EXT 
version here:
http://developer.apple.com/graphicsimaging/opengl/extensions.html
specifically:
http://developer.apple.com/graphicsimaging/opengl/extensions/ext_texture_rectangle.html

It will be a little while before I can test this: my question was 
preempting some porting work, but I'll let you know if there are any 
troubles when I do.

Cheers,
Daniel
