redefiend properties so that min/max are prioritized,
as they are accessed more frequently than pos/size
during rendering calculations.
also introduced miscellaneous functions to improve usability.
Added drawing exceptions when target is not properly ready.
Now, Canvas::update() Canvas::draw() will return InsufficientCondition
if the target has not been set beforehand.
no any 3rd-party libs, such as glfw or glad did not used
support windows, linux, macos and emsdk
only the actually used set of functions are loaded

- C-style strings provide consistent binary interface for FFI
- Reduces potential issues where standard library is limited (e.g., WebAssembly, embedded systems)
Simplified parameters and ensured proper backend engine
initialization by using reference checking through canvas
instances.
C++ API Modification:
- Result Initializer::init(uint32_t threads, CanvasEngine engine)
-> Result Initializer::init(uint32_t threads)
- Result Initializer::term(CanvasEngine engine)
-> Result Initializer::term()
C API Modification:
- Tvg_Result tvg_engine_init(Tvg_Engine engine_method, unsigned threads)
-> Tvg_Result tvg_engine_init(unsigned threads);
- Tvg_Result tvg_engine_term(Tvg_Engine engine_method)
-> Tvg_Result tvg_engine_term()

The following is a redesign that extends the class internally.
The main goal is to preserve the characteristics of the pImpl idiom
for data encapsulation, while simultaneously reducing the memory
allocation overhead typically associated with pImpl.
The stragegy is here:
Rather than alloc the impl memory inside of the thorvg engine,
impl extends the API classes in order to consolidate the memory.
size has been decreased by -4kb with optimization=s

The shadow color produced incorrect results after
blending with the texture color. This was caused
by not taking the alpha value into account in the
specified shadow color (with OpenGL blending disabled).
RenderMethod effects methods would have changes:
+ update() //update the effects if any
- prepare() -> region() //update the effect drawing region
- effect() -> render() //draw the effect
GlRenderTarget contains framebuffer and render target objects,
these GPU resources need to be released before reusing the structure and calling init with the new size.
ThorVG pImpl idiom caused internal data to be scattered
across hierarchical classes. This refactoring consolidates
the data by inheriting pImpl internally, reducing memory
allocation counts and eliminating unnecessary strategy methods.
enhanced the rendering composition target to better support features such as
alpha blending, blending, masking, post effects, and more.
This allows rasterizers to prepare the composition context with more precise control.
Additionally, resolved a crash in the software engine's post-effect process
caused by a buffer size mismatch during XY buffer flipping.

WebGL has a strict rule that does not allow the same GLBuffer
to be bound to both ARRAY_BUFFER and ELEMENT_ARRAY_BUFFER at the same time.
(https://registry.khronos.org/webgl/specs/latest/1.0/#5.14.5)
To support WebGL in the future, a separate GLBuffer is used to store index data.
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

- refactored the Fill matrix to hold internal data statically.
- refactored for clean & neat the raster engine / svg loader logic.
API Modification:
- Matrix Fill::transform() const -> Matrix& Fill::transform() const
