Ideally this would be a format property. In practice it probably works
because we only use 24 and 32 bit depth formats, and the hardware
probably either only distinguishes between 16 and 24/32, or just
doesn't support 32.

It seems the compiler is smart enough to work it out, but strictly
speaking powf() takes floating point arguments.
