As I rewrite some parts of code for color library I noticed silent assumption I made. Namely I assumed that all color components are the same type. But must it be this way? Does anyone use types like:
struct rgb { float r; unsigned char b; signed char g; };
<snip>
So? Allow diffrent types or not?
Although it wouldn't be terribly useful for RGB, other representations may (will?) benifit from this, as a simple example, L*a*b* is represented as an /unsigned/ Lightness, and two /signed/ components, a and b. Someone may wish to represent (or is forced to represent) HSV values with floating Hue, but integral Saturation and Value. Perhaps a specialised graphics application would wish to use (custom?) fixed point types and floating point types in the same value (If consistancy of calculations for Saturation and Value are needed, but accuracy is more important for Hue, for example) In short, I say yea!
