8. GLfloat / GLchan changes:

ctx->Color.ClearColor is now GLfloat[4] too.

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.
