<pre>I found a piglit regression when testing today's master:

mesa: overhaul the glGetTexImage code
1. Reorganize the error checking code.
2. Lay groundwork for getting sub images by passing image offset and
dimensions to the error checking code.
3. Implement _mesa_GetnTexImageARB(), _mesa_GetTexImage() and
_mesa_GetTextureImage() all in terms of get_texture_image().
v2: pass offset/width/height/depth arguments to the error checking
function, avoid using magic width/height/depth values.
v3: remove unused bufSize param to get_texture_image()
