SDL_BYTESPERPIXEL - A macro to determine an SDL_PixelFormat's bytes per pixel.

       This macro is available since SDL 3.2.0.

       Note that this macro double-evaluates its parameter, so do not use expressions with side-effects here.

       FourCC  formats  do  their  best  here, but many of them don't have a meaningful measurement of bytes per
       pixel.
