- /* [dBorca] Hack alert:
- * There is something wrong with this!!! Take an example:
- * 1) start HW rendering
- * 2) create a texture like this:
- * glTexImage2D(GL_TEXTURE_2D, 0, 3, 16, 16, 0,
- * GL_RGB, GL_UNSIGNED_BYTE, floorTexture);
- * glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);
- * 3) we get here with internalFormat==3 and return either
- * _mesa_texformat_rgb565 or _mesa_texformat_argb8888
- * 4) at some point, we encounter total rasterization fallback
- * 5) displaying a polygon with the above textures yield garbage on areas
- * where pixel is larger than a texel, because our already set texel
- * function doesn't match the real _mesa_texformat_argb888
