This set of 3 patchfiles may be applied to Ian's 3.2-3devel tree in
order to get hardware accelerated 3d rendering to work.  The VM now
exports the following two functions: primitiveGetSTDisplay() and
primitiveGetSTWindow().  These are used by the B3DAcceleratorPlugin to
get Squeak's window and display for OpenGL initialization.

I'm not a unix development guru, so I was unable to create a single
patchfile that you can apply at the base of the tree.  You'll have to
change directory to platforms/unix/... in order to apply the patches.

Thanks Bert!
