403710ffbc sw_engine: cleaned up the blending operations. 
Corrected the alpha interpolation order during blending.
This also corrected the hard mix blending result in the guitar sample.

44ca306841 sw_engine: fixed incorrect image blending operations 
The anti-aliased outline color was incorrectly blended
at the multiply option.

The fix can be observed in the example:
'examples/lottie/resourcesguitar.json'

in order to do this, RenderMehthod::blend() method introduced
`bool direct` for figuring out the intermediate composition.

a25366b283 common: spec out Scene Clipper 
Scene Clipper is an unusual feature
that is too unstable and ambiguous in ThorVG.

Users can achieve the same functionality
with multiple composed shapes instead of scene clipping.

4345d6b8a5 API: revise the APIs. 
deprecate the `identifier()` APIs by replacing them with `type()`.

ThorVG is going to introduce an instance `id()`,
and this could be confused with the `identifier()` methods.

with this new type() method can reduce the memory size
by removing unncessary type data.

New Experimental C APIs:
- enum Tvg_Type
- Tvg_Result tvg_paint_get_type(const Tvg_Paint* paint, Tvg_Type* type)
- Tvg_Result tvg_gradient_get_type(const Tvg_Gradient* grad, Tvg_Type* type)

New Experimental C++ APIs:
- Type Paint::type() const
- Type Fill::type() const
- Type LinearGradient::type() const
- Type RadialGradient::type() const
- Type Shape::type() const
- Type Scene::type() const
- Type Picture::type() const
- Type Text::type() const

Deprecated C APIs:
- enum Tvg_Identifier
- Tvg_Result tvg_paint_get_identifier(const Tvg_Paint* paint, Tvg_Identifier* identifier)
- Tvg_Result tvg_gradient_get_identifier(const Tvg_Gradient* grad, Tvg_Identifier* identifier)

Deprecated C++ APIs:
- enum class Type
- uint32_t Paint::identifier() const
- uint32_t Fill::identifier() const
- static uint32_t Picture::identifier()
- static uint32_t Scene::identifier()
- static uint32_t Shape::identifier()
- static uint32_t LinearGradient:identifier()
- static uint32_T RadialGradient::identfier()

Removed Experimental APIs:
- static uint32_t Text::identifier()

0f2fe0c4d4 common: fix rendering failure 
In case of a problem with loading font data, there
is no paint inside a text that can be rendered,
but this should not interrupt the rendering process
of other paints. Now fixed.

a8fc3a6e50 renderer: revise the internal logic. 
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.

54528b6ac9 renderer: introduce a ThorVG Text interface. 
Introduced New APIs under the experimental tags.

- Result Text::text(const char* text);
- Result Text::fill(uint8_t r, uint8_t g, uint8_t b);
- static Result Text::load(const std::string& path);
- static Result Text::unload(const std::string& path);
- static Text::std::unique_ptr<Text> gen();
- static Text::uint32_t identifier()
