From: vandita kulkarni <vandita.kulkarni@xxxxxxxxx> 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. V2: Squashed all the blend color related patches to one single patch and blend func related pathces into one single patch.
