e8cf21a3c9 initializer: add reference counting for the engines initialization.
Introduced the reference counting for the backend engines so that
tvg prevents unpaired engine initialization/termination calls by user mistake.

common sw_engine: revise the masking implementation.
We re-implement the masking feature with image composition method.

This patch is working only for single shape but settle up coming extensions.

7d9023ac5c common sw_engine: code refactoring
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.

common composite: code refactoring
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.

common sw_engine: apply partial composition.
Introduce RendererMethod::renderRegion() to return acutal drawing region info.

That is used by scene composition to composite actual partial drawing region

for better performance.

sw_engine renderer: support scene opacity composition
this is an additional enhancement of af8c278c5e

Now scene opacity composition is supported.

Also, this implementaion fixes an incorrect scene bounding box computation.

Plus, adding stroking feathering to shape bounding box size.

raw_loader Loader: Introduce Raw image loader
Add RawLoader class that loads and display raw images,
and adds a Rasterizer for image data.
Image data can be loaded via picture.
Loaded image supports Composition, Transformation and Alpha blending.

sw_engine shape: performance optimization.
we introduced shared memory pool for avoiding reallocate memory
while it process the stroke outlines, It experimentally increase
the outline data if we use the allocated memory for multiples shape strokes,
we don't need to alloc/free memory during the process.

This shared outline memory is allocated for threads count
so that we don't interrupt memory access during the tasks.

0399d84478 common paint: introduce opacity() method.
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.

@API Additions:

Result Paint::opacity(uint8_t o) noexcept;
uint8_t Paint::opacity() const noexcept;

SwRender & tvgPaint: Implement ClipPath feature (#68)
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

8685c7e0f0 common: fix context corruption among the multiple canvases.
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.

498a024df8 common: ++optimization
replace dynamic_cast to static_cast,

This can be a controversial choice between optmization and clean code.

Obviously we know the converting types,
try avoiding a bit heavier casting some cases.

58de99aea3 common interface: replace arguements size_t to uint32_t
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...

b08d144dc9 common shape: introduce transformation matrix
Paint supports translate, rotate, scale functions for transformation

The origin of these transformation is center of the paint,
thus you have to consider the center-aligned vertices if you'd like to use
these transformation functions.

This policy has been considered for scene transformation.

682bc25298 common shape: revise scale/rotate approach.
Come to think of it, this optimized method is not so useful,
it could just bring the user misunderstanding and
not to efficient as I expected in the most cases.

So, changed policy for transformation behaviors.
it keeps the properties as others but leaves it to the backend implementation.

Plus, this change contains the correct RenderUpdateFlag.
You can refer the flag in the backend to figure out which kinds of properites has been updated
