We introduced separate opacity interface to adjust alpha value by paint.
This opacity will affect to whole paint image if paint is a group of paints.
Also, this opacity is to multipy with fill/stroke alpha values.
This means if the opacity is valid, the paint might deal with a composition step,
which is very expensive due to additional rendering step.
One tip is, if you want to toggle on/off for a certian paint,
you can set opacity to 255 or 0.

common sw_engine: Implement ClipPath feature
Paint object can composite by using composite API.
ClipPath composite is clipping by path unit of paint.
The following cases are supported.
Shape->composite(Shape);
Scene->composite(Shape);
Picture->composite(Shape);
Add enum
enum CompMethod { None = 0, ClipPath };
Add APIs
Result composite(std::unique_ptr<Paint> comp, CompMethod method) const noexcept;
* Example: Added testClipPath
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.
previous implementation didn't consider multiple canvases,
multiple canvas shared one renderer engine that brought corrupted contexts.
Thus, each canvas instances should have designated renderer engine instances.
Now fixed.
Now, stabilizing is pretty enough.
Remove assert code so that we never abort process in any cases.
This also reduce the binary size.

We can use RGBA colorspace rather ARGB for pixel data.
This would be better for many rendering system,
since it's more widely preferred than ARGB including opengl.

we can't control any threads count that could drop the performance.
remove async() and will come back with fine-tuned threading-pool.

Basically, stroke width size is linear,
engine couldn't apply scale factor from the matrix which contains 2 dimensional values.
Thus, we can apply it if the scale factor of x/y is identical.
Otherwise, we should transform every stroke points in the stroking process.
That scenario can be improved with another patch.

this interface is designed for user-defined arbitrary affine-transform paints.
required by svg loader.
