certain systems, may not support file I/O operations.
ThorVG should provide users with an option to configure
builds according to their requirements.
This ensures that file I/O calls are avoided,
preventing potential crashes.
Please use the meson '-Dfile=true/false' option for this.
Please note that "THORVG_FILE_IO_SUPPORT" might be expected
for your thorvg manual build.

Support cross compile the GL backend code into WASM.
The code needs WebGL 2.0 API so, the compile flags contains `MAX_WEBGL_VERSION` and `FULL_ES3`
Also add binding code to initialize the WebGL context and GLCanvas.
- prevent dangling instances in failure scenarios by utilizing a reference counter.
- update the test suite to treat null pointer arguments as invalid argument failures.
Remove the requirement for unique_ptr in the function prototypes.
This change will simplify the API usage, making it more streamlined
and user-friendly. However, memory management will now be the
responsibility of the user.

issue: https://github.com/thorvg/thorvg/issues
Shape's bbox represents only fill's render region.
Render region of fill and stroke is stored in SwTask.
This was visible while rendering shapes with a stroke -
fill was to big.

Since the translate API was used while text updating,
the subsequent range selector transformations gets overwritten
when updating the shape (scale and rotate, adding another
translation will persist). This caused unexpected results.
Fixed by using the transform API when additional transformations
are needed - also fixes applying more than one range selector.
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.
Used native hardware MSAA x4
Full multisampling support including custom blend and compositions.
Must be verified on web and 4K resolution for performance issues
Full review of clipping workflow.
Before we are used separate render target for each clip path and compute shader to find clip path intersections with AND logic.
Now we are using depth buffer and transactions from depth to stencil and back to get AND logic intersections,
Compute shaders, layouts and pipelines was removed
