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);
```

sw_engine: optimize rle clipping 
We don't need to copy the rle data unecessarily,
we can just replace the completed clip rle.

ac1434bb74 sw_engine rleClipPath: Modify clippath spans creation size. 
When updating rle for clipped area, realloc size should be larger than spans size.
so this patch prevents the problem while realloc.

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.

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.

f0ab7f4002 sw common: Fixed crash in rasterRGBA32 
Description:
Crash was observed in examples when composite object was used.
It was caused because __m256i object was used on non aligned
memory to 32bit. Algorithm in this function was changed to use
unaligned __m256i_u object. Code was also simplified.

f1fd23cf32 common render: removed unnecessary assignments in update() fun 
The rotation part of the transformation matrix can be assigned,
it does not have to be multiplied by the identity matrix.
The values of e13 and e23 of the transformation matrix represents the translation,
so they don't need to be taken into account in the rotation part.
