QPainter should support HSL composition modes

There are 4 composition modes which are defined by W3C for CSS compositing [1] and are implemented by other painting libraries: Cairo [2], CoreGraphics [3], and Skia [4]:

• "hue" - hue of source and saturation and luminosity of target
• "saturation" - saturation of the source and hue and luminosity of target
• "color" - hue and saturation of source and luminosity of target
• "luminosity" - luminosity of source and hue and saturation of target
