0a43beb89b sw_engine: fix render fill region 
Shape's bbox represents only fill's render region.
Render region of fill and stroke is stored in SwTask.
This was visible while rendering shapes with a stroke -
fill was to big.

d9be58d4b7 lottie: fix transformations in text range selector 
Since the translate API was used while text updating,
the subsequent range selector transformations gets overwritten
when updating the shape (scale and rotate, adding another
translation will persist). This caused unexpected results.
Fixed by using the transform API when additional transformations
are needed - also fixes applying more than one range selector.

a855666e41 gl_engine: seperate the index buffer from vertex buffer 
WebGL has a strict rule that does not allow the same GLBuffer
to be bound to both ARRAY_BUFFER and ELEMENT_ARRAY_BUFFER at the same time.
(https://registry.khronos.org/webgl/specs/latest/1.0/#5.14.5)

To support WebGL in the future, a separate GLBuffer is used to store index data.

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
