Overview
Note that this macro double-evaluates its parameter, so do not use expressions with side-effects here.
FourCC formats will report zero here, as it rarely makes sense to measure them per-pixel.
Return value
Returns the bits-per-pixel of format .

It is safe to call this macro from any thread.
