We can replace the system logger method by changing single line print source in common,
This also helps to remove the THORVG_LOG_ENABLED macro from each use-cases.
TVGLOG(): To print the hint & tip messages for users.
TVGERR(): To print the error message for debugging.

* svg_loader: allow both clipPath and mask together
* svg_loader: allow both clipPath and mask together fix#1
Changed seperate functions _applyClipPathComposition and _applyMaskComposition into single function _applyComposition
* svg_loader: image tag: force size equal to the viewbox
For some svg files it is needed to force size equal the viewbox
for proper scaling
* svg_loader: image tag: force size equal to the viewbox fix#1
Duplicate declaration of id attribute is invaild.
We do not have a separate policy for invalid svg files.
Therefore, it is a priority to prevent crashes or memory leaks.
If an id is declared as duplicate, the last declared id is used.
This patch introduces embeded <image> tag for svg files.
Images can be now loaded from local path or using data URI Scheme (RFC2397).
Base64 and utf8/uri are welcome.
@issue: #518
Some svg export software puts <defs> element at the end of the file.
If so, the <defs> element won't be found, when parsing <use>.
In such scenario, this patch postpone node cloning until the whole file
is parsed.
@issue: #568
<stop> tag should be always a child of a <linearGradient> or
<radialGradient> element, but there were files with <stop> tag inside <rect>.
This patch fixes a memory leak if no gradient is defined before <stop> tag.
* svg_loader: allow multiple defs without data and memory leak
If the svg file contained multiple <defs> tags, each subsequent tag
overwritten the previous tag. This resulted in incorrect rendering of the
file and memory leaks.

* svg_loader: allow multiple defs without data and memory leak- fix#1
Changed the idea to abandon node creating instead of deleting it after
creation. Removed simpleXmlParseAttributes for _createDefsNode.
Composition can be applied recursively if its children nodes have composition target to this one.
This can be occured by wrong svg description, and tvg prevents this exception case.
@Issue: https://github.com/Samsung/thorvg/issues/494
svg may have 'em' unit for fonts, strtof() must handle this case to not
drop in the infinite loop.
Yet thorvg doesn't support font feature in svg,
it must multiply values with font size if those values have 'em' size.
@Issue: https://github.com/Samsung/thorvg/issues/488
After finding no attributes but white spaces, attrs length could be negative
that resulted in segmentation fault in simpleXmlParseAttributes function.
