The API allows now values <= 0 for dashes and gaps. Negative values
are treated as zero. The exception is when all provided values
are <= 0, in which case the dash is ignored.
This fixes the issue when dash = 0 was provided for strokes with round
or butt caps - the dot was not drawn, even though it should have been.
docs: the strokeDash API behavior's clarification for odd numbers
of values in dashPattern and refinement of the accepted values.
In some clipping cases, the memory allocated for storing spans
was too small. As a result, the entire clipped area might not
have been rendered.
This has been resolved by adding an experimental factor to increase
the size of allocated memory.

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

revert the alpha skip condition introduced in
commit 2990e72b23.
color values with alpha = 0 must be transformed to 0
to ensure correct intermediate composition results.
- 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).
ThorVG did not consider updates to the clipping path
when a paint object was modified after being added to the scene.
This fix ensures that any updates to clipping are correctly
reflected during rendering.

- modify the concept of AABB to apply only to transformed shapes.
- transform points before computing the bounding box min/max
to obtain a more compact shape region.
- trimmming memory by removing the cached matrix, about 36kb
of memory has been reduced per paint instance.
The Emscripten header was previously used because the WebGPU initialization logic was in WgContext::initialize.
Now, initialization occurs at the binding/application level.
added 2 more APIs for user convenience to allow backtracking tree traversal.
API Additions:
- const Paint* Paint::scene() const
- const Tvg_Paint* tvg_paint_get_scene(const Tvg_Paint* paint)
