This implementation uses Ector_Buffer to generate mask image from vg container,
and pass it to Ector engine. Ector renderer could blend this image as a mask.
Yet only vg container works as a mask, we could extend shape to support masking later.
Still vector gl drawing is not completed, We use software ector buffer to draw on it.
This is on progessing.
Ector renderer are created by a factory pattern which return a reference.
The possible logic improvement from here would be to rely on setting the
parent of the object to the Ector_Surface and manage a cache by intercepting
efl_noref to trigger an efl_del of the object or a temporary cache of it.
That's for later.
