30ee03002b sw_engine: fixing stroke gradient 
Instead of checking the stroke's fill, the shape's fill was checked.
As a result the improper rastering function was called (or none).

35fdc9a278 loaders svg: set default color for composition paint. 
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.

903df3da6a loaders svg: prevent composition setting if the result shape is invalid. 
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.

6239eca92f loaders svg: fix invalid clip path result. 
tvg engine expects the valid clippath with valid colors,

f1fe36d8f6 common sw_engine: optimize single rectangle ClipPath. 
If ClipPath is a singular rectangle,
we don't need to apply this to all children nodes to adjust rle span regions.

Rather than its regular sequence,
we can adjust render region as merging viewport that is introduced internally,

All in all,
If a Paint has a single ClipPath that is Rectangle,
it sets viewport with Rectangle area that viewport is applied to
raster engine to cut off the rendering boundary.

In the normal case it brings trivial effects.
but when use SVGs which has a viewbox, it could increase the performance
up to 10% (profiled with 200 svgs rendering at the same time)

Note that, this won't be applied if the Paint has affine or rotation transform.

common picture: fix crash at picture duplication. 
A duplicated picture needs to access internal picture loader data
to get its properties while rasterizing.

But it missed the loader since it's not copied from origin.

Thus, we fix this by sharing the internal loader among the duplications and origin.

623a90de7b common shape: Fixed appendArc for negative values. 
Description:
Fixed appendArc API for -90 angles. In that case it was drawn in wrong
direction.

@Examples

```cpp
  float x = 40.0, y = 40.0;
  auto shape1 = tvg::Shape::gen();

  //OK
  shape1->appendArc(x + 50, y, 25, 0, -91, false);
  //NOK
  shape1->appendArc(x + 100, y, 25, 0, -90, false);
  //OK
  shape1->appendArc(x + 150, y, 25, 0, -89, false);

631c1e5651 loader SvgSceneBuilder: Add root node to clipping viewBox. 
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.
