a48d767cf2 Add a quad 'bufloop' stage to handle glDrawBuffer(GL_FRONT_AND_BACK). 
This removes the notion of multiple color buffers from all other stages.
Will need a bit more work when shaders with multiple render targets arrive.

8b6517abfc don't use driDrawable information directly, don't resize at makecurrent 
driDrawable information now isn't used in most parts of the driver.
makecurrent only updates fb information when the context is new
(driDrawable is still updated by the dri common code).

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.

20cf13e03b Fix screen corruption on resize.

Update cliprects inside the locked region of swapbuffers.

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...
