The GLDirect stuff is really, really dead.  It hasn't been maintained in
years, and it probably hasn't been able to compile in just about as
long.  Moreover, as per discussions in another thread
(http://marc.info/?l=mesa3d-dev&m=131421311903781&w=2), this code is
literally minutes from being deleted.

Since the internal Gallium interface is essentially a clone of the DX10
interface, it should be trivial to make a Gallium DX10 driver.  Note
that this is different from a DX10 state tracker (this is the top-half
layer that makes a particular API available to applications).

One of the Gallium guys should know more...
