Hey,
This didn't look like it should be too difficult, however I have
two worries about my approach
a) the prereq change to move the pixel shader selector,
I should probably move more code, but it might not matter,
but I worry this could have side effects though the ps key
doesn't depend on vs/gs shaders.
b) the spi_sid addition to they key is 8-bits which is a
sizeable key increase, maybe I could avoid this,
Advice on either of these welcome,
This seems to solve:
