Summary:
Here is an additional optmization patch for removing
unnecessary updation of path,
For instance, let's assume this scenario:
If one vg object has 20 path nodes(shapes),
and every single nodes would have 50 path changes.
(like, append_cubic, append_rect, append_xxx ...);
There would 1000 events triggering.
Furthermore, if there are 20 vector objects in one view,
hese events would be triggered 20000 in one frame.
It's insane, actually I could figured out that happens.
and it took a lot of cpu consumption in some vector usages.
efl_gfx_path_commit() is my idea to avoid this.
When path is ready, the path need to get this api call in the last
to make object changed properly.

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.
