For the performance reasons, regardless of the set/default
mask-type value, if the mask is white, the alpha masking is
used. To qualify a mask as white, not only its fill has to be
checked, but its stroke as well. The second was missing.
For the performance reasons, the LumaMask is used only when
it's necessary - when the mask color is other than white.
Otherwise the AlphaMask is enough.
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.
To handle the objectBoundingBox units, the shape's boundaries have to be known.
According to the SVG standard, a stroke shouldn't be taken into account. Since
the bounds() api uses the shape's stroke information, a new function is introduced,
that compensates this and returns boundaries without any strokes.
The final gradient transformation depends on the coordinate system.
It can not be applied during an svg loading. The transformation matrix
has to be passed via api for further gradient processing.
Current paint::bounds() returns the coordinates under the raw status,
the values are not quite useful if the paint object has the transformed children.
Thus, we extends the feature and give an additional parameter "transformed"
to return the coordinates values after transformation by user demands.
This is also necessary for tvg format, since we need the exact view size of the scene information.
The previous api is deprecated and we introduce a new api to replace it.
@APIs:
+ Result Paint::bounds(float* x, float* y, float* w, float* h, bool transformed) const noexcept;
- Result Paint::bounds(float* x, float* y, float* w, float* h) const noexcept;

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.
