The fixed-function blend logic uses the following equation: A + B x C.
A, B and C are configurable and can be complemented with negation (for
A and B) or inversion (for C) modifiers. Let's rework the blending
code to take that into account.
Note that we need to update the checksum of a few traces because the
equations we use have changed, leading to small deviations on the
final images. Indeed, there are several valid options for a given GL
blend equation, but the operand selection probably has an impact on the
rounding, leading to those mismatch.

As drivers have been tested with more and more traces, the yml file is
becoming a bit unwieldy. As more drivers are going to be tested with
traces, and more traces will be used, split them in per-driver files so
the size stays manageable.
