Nope, the i945 has a hardware limit of 2048x2048 for textures and 3d
rendering targets. The i965 has a 8192x8192 limit, but Mesa has a
4096x4096 limit, so I set the i965 driver to that value. At some point,
perhaps Mesa will be fixed to handle larger outputs, but that appears
difficult given the existing Mesa software rendering stack.
