Detailed Description

Complete blending operation definition.

A "blend state" operation controls the math behind certain rendering operations.

The blend math is the familiar OpenGL blend math:

$dst.a = equation(blendFactorDstAlpha*dst.a, blendFactorSrcAlpha*src.a);$

$dst.rgb = equation(blendFactorDstColor*dst.rgb, blendFactorSrcColor*src.rgb);$

Note that when equation is MIN or MAX, the blend factors and constants are ignored, and are treated as if they were 1.0.
