Description:
Crash was observed in examples when composite object was used.
It was caused because __m256i object was used on non aligned
memory to 32bit. Algorithm in this function was changed to use
unaligned __m256i_u object. Code was also simplified.
If a scene has another scene as a child and
the number of children is 1, the composition of the child does not work.
Therefore, fix that composition works as long as the number of children is not 0.
* sw_engine: adding a gradient as a stroke feature
Similarly as a shape may have a gradient fill so can the stroke.
* Capi: adding APIs for a gradient stroke

The rotation part of the transformation matrix can be assigned,
it does not have to be multiplied by the identity matrix.
The values of e13 and e23 of the transformation matrix represents the translation,
so they don't need to be taken into account in the rotation part.
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.

added a routine that draw non-transformed translucent image.
composition images will use this routine to draw faster.
Also added optimization point comments in raster image.
remove the opacity argument in the render method.
Considered again, this opacity value is not commonly used yet.
we can introduce it when it's necessary.
Renamed internal interfaces.
We need both blender & compositor interfaces.
Renamed SwCompositor -> SwBlender which is for pixel joining methods.
Added (SwCompositor, Compositor) which is designed for compositing images.
Splited out ClipPath routine from other pixel compositions'
since yet it's unlikely compatible...
Also revise internal engine interfaces to be simpler.
This is a step forward to enhance masking feature.
The _appendArc function allows to draw angles only in a clockwise direction.
The introduced improvement allows to change this direction by giving the 'sweep' argument
with a negative value.
The wasm is using the ThorVG output starting whith "SVG:" to show
unsupported element and attribute of svg file.
This patch updates wasm_build.sh to make ThorVG prints log,
and removes build errors.

Introduce RendererMethod::renderRegion() to return acutal drawing region info.
That is used by scene composition to composite actual partial drawing region
for better performance.
