Use of 32bit RGB samples, where each component is 8bit, cannot support formats with components greater than 8bit (ex, XRGB2101010). Introduce MAKE_RGBA_64() which creates pixels from a 64bit sample. Each component in a 64bit sample is 16bit long, thus a pixel with 10bit components can be generated correctly.
MAKE_RGBA() can use MAKE_RGBA_64() by scaling each 8bit component to 16bit, for compatilbity.
