7d9023ac5c common sw_engine: code refactoring 
Renamed internal interfaces.

We need both blender & compositor interfaces.

Renamed SwCompositor -> SwBlender which is for pixel joining methods.

Added (SwCompositor, Compositor) which is designed for compositing images.

common composite: code refactoring 
Splited out ClipPath routine from other pixel compositions'
since yet it's unlikely compatible...

Also revise internal engine interfaces to be simpler.

This is a step forward to enhance masking feature.

d3bd55dbc7 sw_engine shape: expand the algorithm to draw arcs with negative angles 
The _appendArc function allows to draw angles only in a clockwise direction.
The introduced improvement allows to change this direction by giving the 'sweep' argument
with a negative value.
