The time remapping logic had an issue where animations with zero value "tm"(Time Remap) were not being processed correctly.
This was happening because the previous implementation only applied time remapping when the value was non-zero. (A zero-value Time Remap should be applied, but is ignored)
The fix changes the default time remap value to `-1.0` (since frame values cannot be negative) and applies time remapping when the value is 0.0 or greater. This ensures that zero value time remapping is properly processed.
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.
The "s" key does not have to appear at the beginning
of the position block. Previously, such cases would
result in a parsing error — now they are handled correctly.

- continue parsing even when encountering parsing errors

revert the alpha skip condition introduced in
commit 2990e72b23.
color values with alpha = 0 must be transformed to 0
to ensure correct intermediate composition results.
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.
- C-style strings provide consistent binary interface for FFI
- Reduces potential issues where standard library is limited (e.g., WebAssembly, embedded systems)
The incorrect line join used for OffsetPath was caused
by changes to the StrokeJoin enum values in commit
34d731fa94. During those
changes, the line join value for OffsetPath was mistakenly
not updated.
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.

Simplified parameters and ensured proper backend engine
initialization by using reference checking through canvas
instances.

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.

The shadow color produced incorrect results after
blending with the texture color. This was caused
by not taking the alpha value into account in the
specified shadow color (with OpenGL blending disabled).
