0a16152d75 api: renamed the composite with mask.
Since we've separated ClipPath and Masking,
Masking now has a distinct and independent purpose.

API Modification:
 - enum class CompositeMethod -> enum class MaskMethod
 - Result Paint::composite(std::unique_ptr<Paint> target, CompositeMethod method) -> Result Paint::mask(std::unique_ptr<Paint> target, MaskMethod method)
 - CompositeMethod Paint::mask(const Paint** target) const -> MaskMethod Paint::mask(const Paint** target) const

2558e5dc10 renderer: introduced SceneEffect feature
Scene effects are typically applied to modify
the final appearance of a rendered scene,
such as adding a blur effect.

Each effect would have a different number of parameters
to control its visual properties. The Scene::push() interface
 uses variadic arguments to accommodate various cases.

Users should refer to the SceneEffect API documentation
and pass the parameters exactly as required for the specific
effect type. For instance, GaussianBlur expects 3 parameters
which are:

- sigma(float)[greater than 0]
- direction(int)[both: 0 / horizontal: 1 / vertical: 2]
- border(int)[extend: 0 / wrap: 1]
- quality(int)[0 ~ 100]

and, scene->push(SceneEffect::GaussianBlur, 5.0f, 0, 0, 100);

New Experimental APIs:
- SceneEffect::ClearAll
- SceneEffect::GaussianBlur
- Result Scene::push(SceneEffect effect, ...);

Example:
- examples/SceneEffect

1fe9f269b1 gl_engine: implement advance blending
Implement some advance blending equation in GLEngine by using two
RenderPass.

* The first pass render the content into an off-screen framebuffer, also
blit the screen content to an off-screen Texture.

* The second pass renders the final blended color to the screen.
Also use a stencil test to prevent non-drawn areas from participating in the color blending calculation.

38697022f0 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.

889d1d1fa2 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()

common: ensure const equality operators
A minor syntactic adjustment to two instances of operator== and one instance of operator!=, both to the end of ensuring these locally-scoped functions are properly identified as const. In the majority of cases, this shouldn't have any impact; however, this change makes these operators play nice in c++20 contexts.
