[Mesa-dev] gallium & texture rectangles

[Luca Barbieri]

I pushed a first version on the gallium-rect-textures branch (not
tested beyond compilation).

As a consequence of the decisions made in this thread, the interface
is exactly identical to OpenGL, and internal drawing code works
exactly as an OpenGL application not requiring
ARB_texture_non_power_of_two would do it (no opinion implied on
whether this is good or not).
