as follows: MAKE_RGB(r,g,b) == rgb_t(r,g,b) MAKE_ARGB(a,r,g,b) == rgb_t(a,r,g,b) RGB_ALPHA(data) == data.a() RGB_RED(data) == data.r() RGB_GREEN(data) == data.g() RGB_BLUE(data) == data.b() RGB_BLACK == rgb_t::black RGB_WHITE == rgb_t::white Implicit conversions to/from UINT32 are built in as well as simple addition, subtraction, and scaling (with clamping). As a result of being a class, some stricter typing was needed in a few places but overall not too much.
