### Support Both 24-bit and 32-bits per Pixel Modes

If you are developing code to support 24-bit true color rendering, be prepared to find controllers in the field that have the true color modes supported as either 24-bits per pixel (3 bytes per pixel) or 32-bits per pixel (4 bytes per pixel). Generally the 32-bits per pixel modes are faster because the pixels can be written with a single CPU double word access, however 32-bits per pixel modes require more memory than the equivalent 24-bit modes. Hence be prepared to find controllers in the field that have only 24-bit modes, only 32-bit modes or both.
