/**
* @defgroup CompositingRules Compositing rules supported by PISCES
* When drawing two objects to one pixel area, there are several possibilities
* how composite color is made of source and destination contributions.
* Objects can overlap pixel fully and/or partialy. One object could be above
* the second one and they both can be partialy or fully transparent (alpha).
* The way, we count composite color and alpha from theirs contributions is
* called compositing rule (Porter-Duff).
* @def COMPOSITE_CLEAR
* @ingroup CompositingRules
* Compositing rule COMPOSITE_CLEAR. This rule applied to destination pixel sets
* its color to 0x00000000 - transparent black - regardless to source color.
* @see setCompositeRule(int), setComposite(int, float)
* @def COMPOSITE_SRC
* @ingroup CompositingRules
* Compositing rule COMPOSITE_SRC. This rule applied to destination pixel sets
* its color to source color - regardless to previous color of destination
* pixel.
* @see setCompositeRule(int), setComposite(int, float)
* @def COMPOSITE_SRC_OVER
* @ingroup CompositingRules
* Compositing rule COMPOSITE_SRC_OVER. This rule is kind of intuitive. When we
* look through transparent green glass bottle at some object, we can see
* mixture of glass and objects colors. Composite color is alpha-weigth average
* of source and destination.
* @see setCompositeRule(int), PiscesRenderer.setComposite(int, float)
