BlendMode MUST BE applied for each combination of blend modes.
But this is not happens when a src = ZERO.
Combination [ZERO, ONE_MINUS_SRC_ALPHA] known as DST_OUT composition operation and used as inverse mask on framebuffer (for producing holes) with soft edge.

This wrong, because only transparent filed can be used for checked for setting blend state.
Any changes of this is BREAKING and need publish new major version.
