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.

8aa12ca468 taskschduler: fix a regression deadlock issue 
This fix introduces a workaround to enforce synchronous tasking on worker threads.
Sometimes, out of threads get stuck in a deadlock condition.

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.

735c1cb9e4 sw_engine: fixed a antialiasing issue. 
Previously, a mechanism was introduced to skip antialiasing computations
when shapes are invisible due to their stroking. However, this mechanism
failed to account for the scale factor of the stroke; it only considered
the current stroke width as a threshold.

Consequently, when the stroke width is scaled up to a value smaller than
the threshold, the incorrect antialiasing approach is applied. This results
in the appearance of jagged edges.

The implemented fix rectifies this problem and ensures that the antialiasing
computation correctly takes into consideration both the visibility and the
scale factor of the stroke width.
