Previously, the engine didn't properly cover the dash line corner styles
because it considered a new line to start at the corner.
This update modifies the logic to recognize curved lines
as a single line, including the corners.
There may still be some quality issues,
but it's an improvement over the previous version.

The color conversion is supposed to take into account the differences between
straight alpha premultiplied color and pre-multiplied alpha color.
The previous logic does not perfectly cover these conditions.
The problem was occured in the thorvg viewer with a jpeg bgra format.
This correction ensures a consistent use of 'ref' and 'unref' for paints to release memory properly.
The memory leak occurred when a picture was not pushed to a valid canvas.
This issue was reported by the unit-test memory sanitizer.
* 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
This fix introduces a workaround to enforce synchronous tasking on worker threads.
Sometimes, out of threads get stuck in a deadlock condition.

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.
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.
