colourTransform is a struct with only one member, a Uint32. The issue with `Uint32`s is that it requires a bunch of bit shifting logic to edit the colors. The issue with bit shifting logic is that people have a tendency to hardcode the shift amounts instead of using the shift amount variables of the SDL_PixelFormat, which makes it annoying to change the color masks of surfaces. This commit fixes both issues by unhardcoding the bit shift amounts in DrawPixel and ReadPixel, and by axing the `Uint32`s in favor of using SDL_Color. According to the SDL_PixelFormat documentation ( https://wiki.libsdl.org/SDL2/SDL_PixelFormat ), the logic to read and draw to pixels from colors below 32-bit was just wrong. Specifically, for 8-bit, there's a color palette used instead of some intrinsic color information stored in the pixel itself. But we shouldn't need that logic anyways because we don't use colors below 32-bit. So I axed that too. |
