Driver throws assertion failure or segfaults with large textures.

Reproduces the errors reported in:

+ * Verify that large textures are handled correctly in mesa driver
+ *
+ * This test works by calling glTexImage2D/3D and glTexSubImage2D/3D functions
+ * with different texture targets. Each texture target is tested with texture
+ * sizes up to the maximum supported texture size. All the calls to
+ * glTexImage2D() and glTexSubImage2D() should ensure no segmentation faults/
+ * assertion failures in mesa driver.
