Status of OpenGL 3.x features in Mesa


Note: when an item is marked as "DONE" it means all the core Mesa
infrastructure is complete but it may be the case that few (if any) drivers
implement the features.

docs: Update GL3.txt. We neglected to list the deprecation model/forward compatible context support. inverse() has been done for a while.

i965: create code path to handle primitive restart in hardware For newer hardware we disable the VBO module's software handling of primitive restart. We now handle primitive restarts in brw_handle_primitive_restart. The initial version of brw_handle_primitive_restart simply calls vbo_sw_primitive_restart, and therefore still uses the VBO module software primitive restart support.
