sw_engine raster: support opacity composition.
This implementation supports shape + stroke opacity composition.
Currently, tvg shape provides individual alpha values for filling & stroking
These alpha values are working individually, meaning that if stroking is half translucent,
user can see that translucent stroking is crossed the shape outlines.
Sometimes this result can be expected but user also expects the shape filling is invisible
behind of translucent stroking.
For this reason, Paint provides an additional api opacity()
that applies opacity value to whole paint attributes.
This is a little expensive job, please consider if you can possibly avoid that usage.
See Opacity example.
