This extension provides four additional blending factors to permit this and other effects: SRC_COLOR and ONE_MINUS_SRC_COLOR for source blending factors, and DST_COLOR and ONE_MINUS_DST_COLOR for destination blending factors. Direct3D provides capability bits for advertising these additional blend modes.
