From: vandita kulkarni <vandita.kulkarni@intel.com>

The below patches support plane and pixel blending
by adding two properties blend_func and blend_color.
As per Damien's initial patches, this design based on
OpenGL's blend equations is suggested by Ville.
All the below patches are tested on BXT android platform.
