@defgroupCompositingRules 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).
@defCOMPOSITE_CLEAR
@ingroupCompositingRules
Compositing rule COMPOSITE_CLEAR. This rule applied to destination pixel sets
its color to 0x00000000 - transparent black - regardless to source color.
@defCOMPOSITE_SRC
@ingroupCompositingRules
Compositing rule COMPOSITE_SRC. This rule applied to destination pixel sets
its color to source color - regardless to previous color of destination
pixel.
@defCOMPOSITE_SRC_OVER
@ingroupCompositingRules
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.
