<li>Massive changes to the Shading Language compiler and related state.
|

|
|
|
<li>Vertex/fragment shaders are compiled into GPU instructions and

programs very similar to GL_ARB_vertex/fragment_program.

<li>The SSE-optimized vertex program path has been removed since it didn't

support more than 12 temp registers, didn't support branching/looping, etc.
