Fix some error:
* glViewport not controlled by framebuffer, and need to set manually when
target framebuffer is changed.
* change even-odd stencil operation, so no need to do third draw call to
clear stencil buffer
* fix the missing `GlCanvas::update` calls in Lottoe and LottieExtension
[issues 1479: Masking, InvMasking, LumaMasking, InvLumaMasking](#1479)
Computes composition and blending using simgle pass istead of two full screen passes
Using a mask (any type) with alpha set to less
than 255 through the fill(r, g, b, a) API resulted
in incorrect compositions of fill and stroke.
Incorrect results were also observed for luma masks,
as their alpha is calculated based on the other color
channels.

* Fix error when handle GradientTransform calculation. And move the inv
calculation into gradient vertex shader.
* Fix cubic tessellation not close the last point
Call the explicit memory deletion—binded in function `delete()`, which is highly recommended by the Memory management in Emscripten guideline.
The function will guarantee that the WASM module is cleaned up from the memory.
see: https://emscripten.org/docs/porting/connecting_cpp_and_javascript/embind.html#memory-management
Additionally, WASM module's initialization part has been refactored to correspond to the change.
The display property was not copied along with other
node properties. This caused incorrect rendering
of an object with display=none if accessed through
a use tag.
This reverts commit 75e587a9a9.
If incorrect data for the points in a polygon is provided,
the element should still be rendered, but only up to the point
where the error occurs—using an even number of the points that
have been successfully loaded.
Selecting a tool without choosing the required tools
resulted in a usage error. Now, the activation
of the appropriate saver/loader for a given tool
is enforced.
[issues 1479: lottie](#1479)
- optimaze stroking algorithm by prevent vector normalizations
- using render meshes heaps to reduce webgpu instances re-creations
- using single instance of pilylines for standard operations such as trim and split
- "on-the-fly" strokes generations with dash pattern
- "on-the-fly" mesh objects generation in a process of path decoding
- merge strokes into single mesh by each shape
The error was visible when multiple shapes were
simultaneously trimmed. The length of a single
shape was zeroed out only in selected cases,
which caused accumulation that could lead to
incorrect extension of the variable determining
the maximum length.

The string passed to the svg parser is not guaranteed to always be a valid string.
Certain strings may have numbers that cannot be converted.
Therefore, make sure to check whether the converted value is in the appropriate range before returning.
related issue: https://github.com/thorvg/thorvg/issues/2078#issuecomment-2037495121
Because memcpy() is not guaranteed to copy null at the end of the data array,
it increase the size by 1 and add null
This prevents invalid access of string functions in parser.
Since blit msaa framebuffer to another msaa framebuffer may generate
GLError in some platforms. Use normal texture rendering to blit the final
color buffer onto target framebuffer.
Note that this change renames the Meson option from 'vector' to 'simd',
separates the NEON types into 'neon-arm' and 'neon-aarch',
and designates the 'mfpu' option solely for 'neon-arm'.
A single animation might have a desinated markers with naming: 0 ~ 0.5 (sector A), 0.5 ~ 1.0 (sector B). Selecting one of them using a marker name(sector A) and could play only that part with animation controllers.
usage:
- `animation->segment("sectionA") // Named segment(Marker)`
- `auto cnt = animation->markerCnt()`
- `auto name = animation->markers(index)`
- `animation->segment(0, 0.5) // Segment`
- `animation->segment(&begin, &end)`

If the command after `m` is not recognized, it must be recognized as `l` or `L`.
However, if it is not recognized after ending with `z`, all commands after it are ignored.
