@ -234,8 +234,9 @@ are some things to change:
Call _swrast_DrawBuffer() too, to update the swrast state.
- Removed swrast->Driver.SetReadBuffer
- Added swrast->Driver.SetBuffer. This function should be implemented by
_all_ device drivers. Mesa will call it to specify the buffer to use
for span reading AND writing and point/line/triangle rendering. There
all device drivers that use swrast fallbacks (and the span functions).
Mesa will call this function to specify the buffer to use for span
reading AND writing and point/line/triangle rendering. There
should be no confusion between current read or draw buffer anymore.

8. GLfloat / GLchan changes:
Changed ctx->Driver.ClearColor() to take GLfloat[4] instead of GLchan[4].
- Changed ctx->Driver.ClearColor() to take GLfloat[4] instead of GLchan[4].
ctx->Color.ClearColor is now GLfloat[4] too.
Changed ctx->Driver.AlphaRef() to take GLfloat instead of GLchan.
ctx->Color.AlphaRef is now GLfloat.
texObj->BorderColor is now GLfloat[4]. texObj->_BorderChan is GLchan[4].
- Changed ctx->Driver.AlphaRef() to take GLfloat instead of GLchan.
- ctx->Color.AlphaRef is now GLfloat.
- texObj->BorderColor is now GLfloat[4]. texObj->_BorderChan is GLchan[4].
This is part of an effort to remove all GLchan types from core Mesa so
that someday we can support 8, 16 and 32-bit color channels dynamically
at runtime, instead of at compile-time.
9. GLboolean ctx->Tranform.ClipEnabled[MAX_CLIP_PLANES] has been replaced
by GLuint ctx->Transform.ClipPlanesEnabled. The later is a bitfield.
10. There's a new matrix_stack type in mtypes.h used for the Modelview,
Projection, Color and Texcoord matrix stacks.
11. The ctx->Current.* fields have changed a lot. Now, there's a
ctx->Current.Attrib[] array for all vertex attributes which matches
the NV vertex program conventions.
