Allow direct updates to the paint object without prior validation.
The verification process is deemed inefficient;
users are expected to ensure the paint is updated using a canvas
that contains it.
This might break the backward compatibility.
dispose of the resources at the end of the paint deletion.
This will help retain the resources of the retained paints
and reuse them after reconstructing the next scene.
ThorVG has offered an option to clear the buffer since version 1.0.
This is essential when users utilize the canvas target buffer
with the main render target. They share the buffer
and need to draw contents onto the existing contents.
API:
Result Canvas::clear(bool free = true)
-> Result Canvas::clear(bool paints = true, bool buffer = true)
Tvg_Result tvg_canvas_clear(Tvg_Canvas* canvas, bool free);
-> Tvg_Result tvg_canvas_clear(Tvg_Canvas* canvas, bool paints, bool buffer);

This correction ensures a consistent use of 'ref' and 'unref' for paints to release memory properly.
The memory leak occurred when a picture was not pushed to a valid canvas.
This issue was reported by the unit-test memory sanitizer.
