[Mesa-dev] [RFC PATCH 00/12] Enable GL_AMD_vertex_shader_layer extension

[Jordan Justen]

A little clarification of the RFC tag for this series.

Patches 1-9: Should be ready, and could be applied separately
Patch 10: I'm working with Chad to verify this better
Patches 11-12: I need more layered rendering tests
