The text node is handled, but default values
of the font-family and font-size as used in
the user's system are not.
For now font has to be loaded by the user.

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

The display property, like any other node's style property,
should be part of a node style. This ensures its correct
copying and inheritance.
For the 'symbol' node, which is not rendered unless it is
used within a 'use' node, the display property can also be
applied. Because of that it cannot be utilized during scene
construction to determine whether the symbol is being defined
or used within a 'use' context.
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.
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.
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.

When finding the 'nodeFrom' referenced by `<use>`,
if it is the parent, it is not referenced.
https://www.w3.org/TR/SVG2/struct.html#UseElement
Specification:
If the referenced element is a (shadow-including) ancestor
of the ‘use’ element, then this is an invalid circular reference
and the ‘use’ element is in error.

Improve parenthesis checking and space checking.
- There must be only one pair of parentheses.
- There cannot be spaces(and ') between id strings.

The three specifications below apply.
Specification: https://www.w3.org/TR/SVG/paths.html#ArcOutOfRangeParameters
-
If the endpoint (x, y) of the segment is identical to the current point
(e.g., the endpoint of the previous segment),
then this is equivalent to omitting the elliptical arc segment entirely.
-
If either rx or ry is 0, then this arc is treated
as a straight line segment(a "lineto") joining the endpoints.
-
If either rx or ry have negative signs, these are dropped;
the absolute value is used instead.
We are introducing the FontLoader, which slightly differs
from the ImageLoader in terms of features. To adequately
support both, we have separated the loader functionalities
into FontLoader and ImageLoader. This allows us to optimally
adapt the LoadModule for each case.
The loader cache is applied to conserve memory.
If the input data is already present in loaders,
the loader cache will promptly return the active loader.
This results in a lot of memory savings for the duplicated resources.

I've added new parameter, const string& resourcePath, to load external image on lottie.
Result load(const char* data, uint32_t size, const string& mimeType, bool copy, const string& resourcePath)
Note: tvgLoadModule will have new overrided method `open`, not to effect to other changes except animation.
