[issues 1479: ClipPath](#1479)
Supports ClipPath composition.
Clip path composition is an only composition type who doesn't ignore blend method.
Clip path is a combination of composition approach and blend approach using compute shader
LottieRenderPooler is designed to manages rendering
instances(paints) efficiently through a simple pooling
mechanism to resuse among the animations
This replaces the previous individusal paints implemenations
among solidfill, precomp vierport and pictures,
also fix a potential paints corruption problems.
This patch provides initial support for the text range selector. Full support will be added gradually in subsequent steps. This is the first step.
Text range selector with following properties:
1. Text Range Selector (Units)
2. Text Style
- Fill Color
- Fill Opacity
- Stroke Color
- Stroke Width
- Stroke Opacity
- Opacity
- Rotation
- Position
- Scale
In the function calculating the tangent to a cubic bezier
at a given t, the atan was calculated using dx over dy,
instead of dy over dx. The error was visible during
the animation using auto-orient = true.
This corrects the return value to Result::InsufficientCondition
when a custom transform is applied.
Additionally, unnecessary x and y member fields have been removed.
comp pointer is used for checking if the header is ready.
It can be written in a worker thread and needs a critical
section on the reader side.
This also potentally improve the thread efficiency
from the segment() / marker() function calls.
loader->stack.pop() at line 3271 is called to remove
the defs node added to the stack due to nested graphics elements.
However, it is called in an inappropriate situation and the loader's node tree is damaged.
Fixes an error where the close tag is recognized as a `line` of the graphics tag when it is `linearGradient`.
ex)
```
<defs id="def">
<linearGradient x1="1" y1="2" x2="3" y2="4" id="l"/>
</linearGradient>
<rect x="10" y="10" width="10" height="10" fill="blue" id="r2"/>
</defs>
```

deprecate the `identifier()` APIs by replacing them with `type()`.
ThorVG is going to introduce an instance `id()`,
and this could be confused with the `identifier()` methods.
with this new type() method can reduce the memory size
by removing unncessary type data.
New Experimental C APIs:

New Experimental C++ APIs:
- Type Paint::type() const
- Type Fill::type() const
- Type LinearGradient::type() const
- Type RadialGradient::type() const
- Type Shape::type() const
- Type Scene::type() const
- Type Picture::type() const
