Hermet Park 38697022f0 sw_engine: fixed incorrect image blending operations
The anti-aliased outline color was incorrectly blended
at the multiply option.

The fix can be observed in the example:
'examples/lottie/resourcesguitar.json'

in order to do this, RenderMehthod::blend() method introduced
`bool direct` for figuring out the intermediate composition.
