b2r2: Add support for blending on background image
Instead of blending only on the destination there is now
a possibility to blend on a supplied background using standard
blending flags. The background blending option is enabled through
setting a flag in the request. When background blending is enabled
the destination blending is omitted and the destination buffer is
simply overwritten.
