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:
![\[
dst.a = equation(blendFactorDstAlpha*dst.a,
blendFactorSrcAlpha*src.a);
\]](form_1_dark.png)
![\[
dst.rgb = equation(blendFactorDstColor*dst.rgb,
blendFactorSrcColor*src.rgb);
\]](form_2_dark.png)
Note that when equation is MIN or MAX, the blend factors and constants are ignored, and are treated as if they were 1.0.
