If stop is declared immediately after Gradient is closed, the stop is registered in latestGradient.
Change latestGradient to a Stack and add a stop only to the last added gradient.
When that gradient is closed, no more stops should be registered for that gradient.
And gradients do not allow nested declarations, so only the earliest declared Gradient is valid.
Support the bindings to be more integrable with a system's coherent memory management.
Pleaes note that thorvg now only allow the desinated memory allocators here:
malloc -> tvg::malloc
calloc -> tvg::calloc
realloc -> tvg::realloc
free -> tvg::free

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.

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 directive is used to give a specific style property
higher priority, ensuring that it overrides other style
declarations for the same property.

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.

Till now only the grad stops were inherited. Now all
grad attribs are.
Inheritance from different grad type is not supported.

* 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.
Defs can be defined at the end of the file. In such a case each
node with a defined class attribute has to be marked and checked
at the final stage of processing - the proper style node has to be found
and its style has to be applied.
Function simpleXmlParseCSSAttribute() used to parse the data inside the style tag.
For now the supported formats are: tag {}, .name {}, tag.name{}
_svgLoaderParserXmlStyle() used to deal with the results of the above - to create
the proper nodes. Will work after create...Node() are changed.
Note:
The geometric attributes are not copied from the node defining the style
to the node using it. The SVG2 standard has to be checked to decide
whether it should be supported.
For now it is assumed that only one style element is defined
in an svg file, although it can be easily changed if needed.
The style node will be used to define the style applied to a node
of a given type or in a case when a class attrib was used.
It's the first step in introducing the css inline style sheets into tvg.
For now the class attribute is set only for SvgNodes (not for grads),
it's not used yet.
In an svg file the mask-type attribute can be specified.
It takes one of the two values: Luminosity or Alpha.
After the LumaMask is introduced into TVG, this attribute can be
properly read by the svg loader.
The SvgCompositeNode is replaced by the SvgMaskNode and SvgClipNode.
This is needed for using Luma/AlphaMask in the svg loader and in the future,
when we introduce other mask's features.
Clips and masks require to implement some additional variables,
so the new node type has been introduced. Implementation of the usage
of these additional variables will be the subject of a separate
commit.
