34f6243bef Improve this demo in a few ways. 
1. Use more reasonable hither/yon clip planes to make better use of shallow
(16-bit) z buffers.
2. Use different colors on cube faces to help detect Z fighting if it occurs.
3. Report GL_DEPTH_BITS on start-up.

aac2129663 Fix broken depth offset. 
The edge vectors were totally wrong.
Need to multiply bias units by the min resolvable depth delta.

Update cliprects inside the locked region of swapbuffers.

fb67b1609e remove bogus assertion, change drawable updates 
don't update driDrawable information until later at all
(blit needs fixing).

43e24ff507 some fixes, fake frontbuffer 
still doesn't work quite right (resize).
Fake frontbuffer doesn't copy in real frontbuffer.
Don't even think about doing rotation/page flip/triple buffering for now...
More cleanups needed (fake cliprects etc.)

a49a23efc5 Fix line clipping bug. New comments. 
Need to use a new prim_header for the post-clipped line.  Otherwise,
we were changing the header passed to us from the vb code.  That messed
up the vertex pointers for the next line primitive.

1deafdb1de Do depth testing with integer values. 
Using floats (and float->ushort->float conversion) introduces errors.
Only GLushort depth buffers work for now...
