blending of sf::color functionality

[kingnobody8]

Hello!

Recently I watched this video on computer color blending

I went ahead and added proper blending functionality to my local copy of sfml. Would anyone be opposed to getting this functionality integrated into the mainline?

To clarify, the functionality is a static function in sf::color whose definition looks like this:

static Color Blend(const Color& c1, const Color& c2, float lerp);

Color blending is such a complex subject. I found myself needing either interpolation in RGB space, or in HSV space, depending on the project and what I wanted to achieve. I don't know what your video explains (didn't watch it), but you'll always find someone who needs a formula that is not the one you programmed into your library.

The video describes how an image stored digitally is "gamma-affected" and manipulating on that data before its transformation back to normal (the colour transformation by colour scheme and monitor adjustments) is "incorrect".

Its suggestion appears to be "apply the gamma-correction/colour-scheme first, make modifications, then undo the gamma-correction/colour scheme so that when it is finally displayed using the colour scheme, it appears correct."

Is this the sort of thing that you have implemented?
