I guess, when alpha is in the low bits, you could do something like:
reinterpret(UInt32, UInt32(rotate_left(pixel))) # given that function was
but I guess it would be slow.. ROL (I'm justed to from assembly) couldn't
be optimized away, in most or even any cases..
I'm not sure why, there are just [arithmetic] shift left and right in Julia
and languages I'm familiar with.. I guess because you can build from that
Not sure that version would be easier for the optimizer..
Best would be if there already is already also a RGBA32 type (or you could
