Having the driver expose this new extension is how I tell that the
driver is going to actually call the __DRIimage-based loader; the
alternative to a new extension would be to stick a flag in the
__DRI_CORE structure.

It defines the interface to a driver which will be using the image
loader to allocate color buffers if available. The fact that the image
loader and DRI2 loader can both share the same driver interface is a
happy coincidence.
