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.
Issue: #1793
The custom implementations of 'strtof' and 'strndup'
present in the svg loader have been moved into a new
'utils' directory (strToFloat and strDuplicate, respectively).
The directive is used to give a specific style property
higher priority, ensuring that it overrides other style
declarations for the same property.
@Issue: https://github.com/thorvg/thorvg/issues/1255
The custom _strndup was used only in one file
as an internal function and wasn't accessible
in other parts of the code. Now function
is available as svgUtilStrndup.

In the case when a 'use' node was used
in a 'defs' block and the element it
referenced was also defined within the same
'defs' block, the reference node could not
be cloned. This was because the 'defs' node
could not be located.

The conversion to percentages was applied twice.
Additionally, when a viewbox value was provided before the width/height,
incorrect scaling occurred.
@Issue: https://github.com/thorvg/thorvg/issues/1414
The percentages should refer to the size of the viewbox.
This was not the case for not knowing the viewbox before
reading the width/height.
@Issue: https://github.com/thorvg/thorvg/issues/1409
Self-closing tags (empty elements) were parsed until
the appearance of the '>' character, causing the '/'
char to be appended to the tag name. The final '/'
char should be omitted.
Till now only the grad stops were inherited. Now all
grad attribs are.
Inheritance from different grad type is not supported.
@Issue: https://github.com/thorvg/thorvg/issues/1209
Svgs without any viewbox and width/height information
have to be loaded before any other action is taken.
This is necessary to get the valid sive/viewbox info.
For svgs with the width and/or height value set to zero
rendering was disabled - the load api return Result:Unknown
and draw - Result::InsufficientCondition.
Now an empty scene is added, so that both, load and draw,
return Result::Success.
* svg_loader: preserveAspectRatio attrib handled according to the svg standard
* svg_loader: symbol fixed
The correct width/height values used in the _useBuildHelper function.
Bug was propageted while the preserveAspectRatio attrib was handled,
now fixed.
* svg_loader: refactoring code regarding the preserveAspectRatio attrib
To avoid copy/paste a new function is introduced to handle the proper
scaling.
* svg_loader: initialize the svg loader members
The 'align' and 'meetOrSlice' svg loader members were not initialized.
* svg_loader: resize function forces any transformation
The resize function is called after the svg image is read and scaled
taking into account the proper preserveAspectRatio value. While resizing
the preserveAspectRatio isn't checked any more and the image can be
freely transformed.
