BTW, this doesn't work with NVIDIA's driver.  The proxy texture size 
test is indicating that a 2K x 2K x 2K texture is possible but when we 
actually try to create and fill that large of texture my machine swaps 
like crazy and eventually the test crashes.  I think their proxy 
texture test is being a little too generous.
