<pre>I noticed your drivers are advertising support for blend_advanced and
blend_advanced_coherent, but couldn't understand why it still didn't work. I
traced it down to you enforcing that fragment shaders needs to enable which
advanced blend equation they work with, something the NVidia driver does not.
I think it would be in your best interest to only warn on that and not abort
the operation. If you can't do it correctly without that hint, that is of
course acceptable, it is there for a reason, but it seems you are only doing
the validation for the sake of strictness, and that is hurting your drivers
compatibility.</pre>
