At the moment this code is called to fall back to  'legacy' color fill
/ clear related calls and that's also what I intend to use it for in
blit_shader. I'm not sure if we should handle 128-bit float support in
the fallbacks. I agree that later on perhaps we could make this
function more generic. The move to utils.c is a first step. The same
can be said about the blit_shader fill_color which can later on also
be extended if we want to use it from device.c but I don't think it is
wise to change it all in the first iteration.
