0947c05a52 sw_engine: replacing a cast with rounding
Casting a float to an int instead of rounding resulted
in a visibly incorrect reduction of the rendered area.

97817bedfe lottie: support for firstMargin < 0 in text follow path
The first margin value shifts the starting point where the text
begins along the path. Now cases where firstMargin < 0 are handled,
for both closed and open paths.

Added drawing exceptions when target is not properly ready.

Now, Canvas::update() Canvas::draw() will return InsufficientCondition
if the target has not been set beforehand.

of the position block. Previously, such cases would
result in a parsing error — now they are handled correctly.

2d695c4d46 example: disable vsync of sw window for stability.
SDL + software engine doesn't need the vsync?

Observed the rendering performance is noticeably unstable on Intel Arc chipsets
with certain window sizes (ie 800x800) when VSync is enabled on software-rendered windows.

This might be a workaround, or it could be an issue with the driver or SDL.

Either way, the SDL + software engine doesn't need VSync.

65c4e27437 svg_loader: fix clipping in use/symbol nodes
Clipping for the <use> node when a <symbol> was used,
was being overridden when 'overflowVisible' was 'true'
(the default value), which caused the 'clip-path' applied
to the <use> node to have no visible effect.
The clipping for the <use> node (without <symbol> node) was
transformed in an incorrect order, resulting in a visually
incorrect results.

53e5e783b7 api: revise engine initialization and termination
Simplified parameters and ensured proper backend engine
initialization by using reference checking through canvas
instances.

C++ API Modification:
- Result Initializer::init(uint32_t threads, CanvasEngine engine)
 -> Result Initializer::init(uint32_t threads)
- Result Initializer::term(CanvasEngine engine)
 -> Result Initializer::term()

C API Modification:
- Tvg_Result tvg_engine_init(Tvg_Engine engine_method, unsigned threads)
 -> Tvg_Result tvg_engine_init(unsigned threads);
- Tvg_Result tvg_engine_term(Tvg_Engine engine_method)
 ->  Tvg_Result tvg_engine_term()

1a332acd37 renderer: revise the pImpl design with a better efficiency
The following is a redesign that extends the class internally.

The main goal is to preserve the characteristics of the pImpl idiom
for data encapsulation, while simultaneously reducing the memory
allocation overhead typically associated with pImpl.

The stragegy is here:
Rather than alloc the impl memory inside of the thorvg engine,
impl extends the API classes in order to consolidate the memory.

size has been decreased by -4kb with optimization=s
