glvideomixer: implement glBlendFunc and glBlendEquation

Allows more blending options than just A over B

e.g. frame comparisons are now possible.

    sink_0::zorder=0
    sink_1::zorder=1
    sink_1::blend-equation-rgb={subtract,reverse-subtract}
    sink_1::blend-function-src-rgb=src-color
    sink_1::blend-function-dst-rgb=dst-color
