453cba7ddd gl_engine: make GlRenderTask generic with uniform block 
* Use uniform block to pack all color informations
* Move the actual gl draw call into GlRenderer::sync function, so all
  data is been uploaded into GPU
* Make GlRenderTask simple and generic for direct gl draw

9e3b74bac5 sw_engine fill: fixed radial fill focal issue. 
This might be a workaround to correct the issue.
The threshold value comes from the mathematical inaccuracy.

ec5a32bb73 lottie: enhanced the colorstop feature. 
Lottie ColorStop RGB / Alpha can be dealt with individually.
Since thorvg handles this one unified set,
lottie model need to merge the data into one structure.

cba2b0f724 lottie/builder: correct a parenting error. 
There is a missing case where a layer didn't parent properly,
especially when the parent is the matte target.

5b8c66f5c8 lottie/builder: fix an invalid matting result. 
Previously, it ignored the matte when it was out of frames for the sake of optimization.
However, this led to an incorrect matting result.

It should make the scene invisible when the matting is invisible.

2cada9c446 loader/lottie: code refactoring. 
migrate transform from the group to the layer.
transformation is not necessary in group but layer.

This helps to reduce the unnecessary assigning of the transformation
in group instances.

d683d2e70d sw_engine: Do not handle exceptions for zero line length. 
While it may represent a dot with a stroke width,
ignoring its length is not a good idea.

this also eliminates 0 size dash dots caused by unexpected empty lengths.
