/** Returns a pointer to a new image, based on 'surface'
but with changed hue. Changing the hue means to "rotate"
the color spectrum. You can read more about the HSV color
model on the Internet.
This method is used to change the color of a sprite
(e.g. a car or another object). I suggest to make the
basic images in a red color-spectrum and create all
other colors from it.
For examples, please visit the Trophy homepage developer
