Skip shapes rendering, if opacity is 0 and if fill color for shape and strokes also equal to 0
This behavior is used in sw renderer and fix visual artifacts in referenced animations.
Also this rule fix composition results in case of AlphaMask and InvAlphaMask methods
Providing an incorrect mimetype or not specifying one
was not handled and resulted in data not being loaded
when loading the font from memory.
Now, the use of the TTF loader is enforced regardless
of the provided mimetype.
it provide changes public API for webgpu canvas interface to provide nessessary handles to native window for different platforms:
API Change:
- Result target(void *instance, void *surface, uint32_t w, uint32_t h) noexcept;
* Optimize clip logical, change to use GL_GRATER and keep incrace depth
value, so no need to do depth clear after every clip draw.
* Correct geometry bounding box calculation, and make sure the bounds is
larger than all vertices
* Limit drawing area for off-screen RenderPass with correct scissor box
this optimization applies when the clipper is
not an axis-aligned rectangle under the following conditions:
a. Coverage where the clipper is a regional superset of the viewport.
b. Coverage where the clipper is completely outside of the viewport.

When checking the fastTrack condition,
it's necessary to exclude the outlines
with a Bezier curve (Move-Cubic-Line,
Move-Cubic-Close, Move-Line-Cubic).

NonSupport indicates unsupported options due to disabled features
or lack of system support. InvalidArgument indicates the case
such as incorrect parameter values.
For the 'simultaneous' trimming option, the maximum
stroke length from all subpaths was determined and
used to scale the trim of each subpath. As a result,
if the subpaths had different lengths, this scaling
was incorrect.
Now, the length is determined separately for each
subpath and is used to scale the trimming of its stroke.
@Issue: https://github.com/thorvg/thorvg/issues/2335
The functions setting stroke's features always
returned a true. Returnig a boolen was a remnant
from a previous implementation. Since now they
never return false, they can be void functions.
The APIs description has been corrected.
New api sets/gets the trim of the stroke
along the defined path segment, allowing
control over which part of the stroke is
visible.

In a case of usage stencil buffer only we need to turn off an color target writes. In other case color buffer fill be filled by unxepcted color if fragment shader did not return any value.
It happens in a case on OpenGL realization of webgpu, that used in linux

Rather than aiming for extremely high accuracy,
a compromise can achieve with better performance.
This modification helps prevent unnecessary image rotation.

[issues 1479: Fill Rule](#1479)
In this solution we dont need to find silhouette, that is not a cheep operation (decreasing performance in 2 times)
For winding, you can select separate operations for front and back faces (increment for front, decrement for back)
After rendering the fan, the value in the stencil buffer will be the winding number. You can fill the appropriate portion by rendering a screen-sized quad with stencil testing enabled and the stencil function set according to which winding rule you wish to use.
For even-odd, you don't need to distinguish front and back faces; you can just use INVERT as the operation.
