[Piglit] [PATCH] Added a test that checks if program have allocated more memory than allowed that program get correct gl_error. From the ARB_texture_buffer_object extension spec: While buffer textures can be substantially larger than equivalent one-dimensional textures; the maximum texture size supported for buffer textures in the initial implementation of this extension is 2^27 texels, versus 2^13 (8192) texels for otherwise equivalent one-dimensional textures.
