c57e2e6c9f wg_engine: multisampling support 
Used native hardware MSAA x4

Full multisampling support including custom blend and compositions.
Must be verified on web and 4K resolution for performance issues

0815366763 wg_engine: clippath optimization 
Full review of clipping workflow.

Before we are used separate render target for each clip path and compute shader to find clip path intersections with AND logic.
Now we are using depth buffer and transactions from depth to stencil and back to get AND logic intersections,
Compute shaders, layouts and pipelines was removed

dfd7693158 lottie: offset does not depend on shape direction 
According to tests in AE, the offset direction should
not depend on the direction of the shape. A positive
offset value expands the shape, while a negative value
contracts it. Fixed.

d9bbd433e8 lottie: correct the array reserved size 
The color input will contain at least colorStops.count * 4
elements (not including alpha). Since the alpha offset values
don't have to much colorStops, estimation is used.

78285e1cfd lottie: fix offset 
For long Bezier curves compared to the offset value,
the offsetting algorithm caused deformation. The problem
became evident after adding mask extension, as the simple
shapes defined there are based on Bezier curves rather
than as shapes like a circle/rect/etc, which is the case
for the offset. Now fixed.
