Previous masking image is generated on vg rendering time,
though context is changed to main vg rendering to masking,
This had a issue that ector context switching which is not allowed
in software backend because of asynchronou method.
Now, this improvment brings the masking rendering move to
vg render pre step with synchronous rendering method,
then use the masking surface in the main vg rendering.
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.

Dectected huge amount of unnecessray internal events triggering
which were signaled via vg nodes.
By events, nodes were connected with each others,
and finally reaches to vg object to update its rendering properly.
However GFX_PATH_CHANGE signal is too commonly triggered for scenarios,
listening and response it is too burdensome.
We acutally don't need to do this if all nodes could share the
vg object. Nodes directly notify vg object to update it.
Next patch will come to remove stupid GFX_PATH_CHANGE that's aweful
in performance wise.
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.
