[Mesa-dev] [PATCH] mesa: Strip texture border for proxy texture as well

[Anuj Phogat]

Intel and Gallium drivers don't support texture borders. Border is stripped
before texture is used inside the driver. So, glGetTexLevelParameteriv()
returns the stripped values of texture dimensions. But it returns un-
stripped values for proxy textures. This patch adds strip_texture_border()
for proxy textures as well.

A piglit test case for this patch will be posted on piglit mailing list
for review.
