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.

@Examples: Duplicate

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.

5e01fd8b4b Revert "sw_engine shape/image: substituting logical 'and' with 'or'" 
This reverts commit 74b27c74af.

This patch breaks Stroke example. 1 line drawings...

There is a possibility that less 1 (i.e: 0.5) width axis-aligned line drawings...

So logically "&&" is correct.

355cc8c253 svg_loader SvgPath: Remove unnecessary optimization code 
This condition(optimization) is not a step suggested by arc implementation.
https://www.w3.org/TR/SVG11/implnote.html#ArcCorrectionOutOfRangeRadii (Step2)
This code is useful if the arc is too small to represent.
However, scaling often occurs in vectors, which can create unnecessary problems.

example path
<path d="M32.41,20.49a.41.41,0,1,1-.41-.42A.41.41,0,0,1,32.41,20.49Z" transform="translate(0)" fill="#020202"/>

sw_engine fill: fix wrong gradient transformation 
There transformation logic was not identical between shape & gradient

gradient transform was applied into center of gradient world,
while shape wasn't. So... we correct gradient transform metric to shape like.
