These new apis would enable users to easily modify the motion scene,
The data structure of the paints has been changed from an array to a list.
@APIs:
std::list<Paint*>& Canvas::paints() noexcept;
std::list<Paint*>& Scene::paints() noexcept;
@Deprecated:
Result Canvas::reserve(uint32_t size) noexcept;
Result Scene::reserve(uint32_t size) noexcept;
@Issue: https://github.com/thorvg/thorvg/issues/1203
When shapes are poped from canvas while retaining shapes instances,
they have no chances to redraw after pushed again due to missing flag.
This patch fixes it by forcely updating flag on pushing time.
@Issues: 181
Canvas::clear() introduces a new argument "free" that deterimes freeing the retained paints.
If free is true, Canvas won't delete the retained paints so that user keep paints valid.
In this scenario, user must have paints pointers, free them manually or push them again to the canvas.
This scenario is useful if user wants to re-organize paints order in the list or reuse them.
we should avoid code insertion during file dependencies,
such as #include "xxx.h" which has implementations.
This could increase binary size, we can avoid it as possible.
Current patch improves binary size like this:
From: file(2059008) = text(120360) data(8096) bss(80) dec(128536)
To : file(1921832) = text(118429) data(7872) bss(56) dec(126357)
More additional patches will come in to optmize binary size.
remove unnecessary condition.
implementation won't be included multiple times not like headers.
Thus this condition is unnecessary.

1. removed async option which doesn't work currently,
rather than it, we can add async option in initiailizer class.
2. removed update() method.
Instead, we can call update(paint = nullptr); which has exactly same behavior.

We prefer to build up a tiny compact engine at memory rather than compatibility,
this engine is not considerd for end-users but designed for middle-level framework
and some low-level users.
Thus, we won't consider 64bits data size,
use explicit 32 bits data until coming next upgrade...

Introduce Result type for notifying caller more detailed info.
We should implement the result values for each apis, with practical values.

hide engine() interface of shape that's not friendly one by users.
instead canvas would access shape internal data to update/draw it.
Now Paint cannot update itself but has to request to Canvas for it.

PaintNode -> Paint
ShapeNode -> Shape
SceneNode -> Scene
We can keep clean and neat shorter names.

Obivously, we need to clear target before drawing.
Thus canvas request to renderers to clear buffer.
the implementation is upto backend engines.

This allocates nodes slots in advance to avoid memory grow & copy.
it will be benefit if you know how many shapes will be used in your canvas.

introduce Canvas class to replace the CanvasBase.
now, SwCanvas, GlCanvas inherits this Canvas for polymorphism
and remove duplicated interfaces.
