This implements support for a very new extension to ES, which allows you
to do dual source blending just like in desktop OpenGL.
This works with the piglits that I am writing that just need to be cleaned
before they are pushed, and it also works fantastically with the
Dolphin emulator (Only known application that uses this extension)
Ryan Houdek (8):
Add EXT_blend_func_extended XML definitions
Add required variables to _mesa_glsl_parse_state for
EXT_blend_func_extended
Add support for the new builtins that EXT_blend_func_extended
provides.
Add a parse check to check for the index layout qualifier
Enable usage of blend_func_extended blend factors
Allow MAX_DUAL_SOURCE_DRAW_BUFFERS to be available to ES
Add EXT_blend_func_extended functions to the dispatch_sanity test
Enable EXT_blend_func_extended if the driver supports the ARB version
