2bf4a500de Fix for-loop in interp() so we don't go out of bounds. 
Improved comments for that loop.
Added some sanity check assertions regarding vertex layout.

5810b40d6e set INTERP_CONSTANT when appropriate 
Not really signficant now since draw_flat stage copies the provoking
vertex color to all prim verts.

60a21f6c54 Simplify slightly. 
Don't bother trying to save a small memcpy.

f0f9a22609 minor changes, comments about multiple color buffers, MRT. 2007-07-12 16:17:14 -06:00
Brian
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.

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

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...
