* However, when the texutre size is large, things become unstable. We
* require the maximum texture size to be 2^30 bytes in
* screen->can_create_resource(). Since the maximum pixel size is 2^4
* bytes (PIPE_FORMAT_R32G32B32A32_FLOAT), textures should not have more
* than 2^26 pixels.
*
* For 3D textures, we have to set the maximum number of levels to 9,
* which has at most 2^24 pixels. For 2D textures, we set it to 14,
* which has at most 2^26 pixels. And for cube textures, we has to set
* it to 12.
