This change protects against negative value in unsigned int of
RenderRegion.x/y. This fixes a problem of invisible paint if ClipPath
bounds was negative.
@issue: #704
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
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
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
The ColorStop offset < 0 and > 1 should be treated as 0 and 1 respectively.
The offset value < than the previous offset value should be replaced
by the previous value - without this change segfault occurred.
Validating the APIs parameters values is the user responsibility.
The loader was ready to handle the gradient stroke, but there was no API to support
it when the loader was introduced. We've had this API for a while already, so
its call has been added.
We are doing enough calculations in the parser if the unit is user space.
This causes the cx,cy coordinates of radial gradient to be calculated incorrectly.
So remove it.
Calculation of objectBoundingBox case in linear gradient is incorrect code.
This causes the x,y coordinates of the linear gradient to be calculated incorrectly.
So remove it.
For now the bounding box of all the shapes was established and if it was larger
than the viewBox of the SVG, the clipping layer was added. The bounds api
returns the rectangle that encloses the shapes before any transformations.
So comparing it with the viewBox doesn't make sense. The comparison is removed
and the clipping layer is always added.
1.
Modify that attribute information used for use type
looks like it was used for g type.
2.
Fix clippath node looking like setting "none"
(clippath's display = false is intentional)
If no viewBox attribute is given, the height and width attributes are used
to establish the viewBox size. However, this information was not available
inside the scene builder, even though it was needed.
not only clippath but alpha compositions might also have any valid color.
Set it default and let it override values while appending shapes if it's necessary.
Current loader could return invalid shapes -default, from _appendShape()-
by a certain interpretation result,
Though it's a wrong or exception case, we can prevent worse case by avoiding it.
If the boundary of scene created through the scenebuilder is larger than the viewbox,
scene(SVG's root) should be clipped to the size of the viewbox.
So, if scene need a clip, add a parent root and add clippath composition to that root.
This Array is promoted from SvgVector to use it widely in tvg.
It's similar with std::vector, we can use it instead of it.
Also, svg_loader replaced with it subsequently.
* common Picture : Introduce Picture's size setter, getter APIs
If picture or file loaded by picture has an explicit Size(width, height),
it is transformed to fit the size.
