d70ddcd67c lottie/text: Fix incorrect text range without end condition
Improving text render compatibility by fixing wrong Text Range.

When lottie doesn't have `end` prop in the range, system must ignore condition regarding to `end`.

The original logic unintentionally swaps `start` and `end` prop, because `end` is the zero in this case. Then the text range animation behaves the opposite.

b0683a26ec api: Introduced Paint::clip() API
Separate clip function from the Composite()
clipping and composition can be used together.

This helps avoid the introduction of nested scenes
when composition and clipping overlap.

Deprecated:
- enum class CompositeMethod::ClipPath
- enum Tvg_Composite_Method::TVG_COMPOSITE_METHOD_CLIP_PATH

Experimental API:
- Result Paint::clip(std::unique_ptr<Paint> clipper)
- Tvg_Result tvg_paint_set_clip(Tvg_Paint* paint, Tvg_Paint* clipper)

9c5933a4e5 lottie/text: applied Text Range randomization.
on each parse, if the `randomize` is enabled,
the start and end of the Text Range are redefined
with the same gap as the original range.

87d85047aa lottie: add offsetPath support
Due to the lack of an analytical solution for Bezier
curves offsetting, a simple and computationally cheap
approximation has been implemented. The algorithm shifts
the segments connecting control points and determines
new points based on their intersections.

09313ae307 lottie: fix text update
The occurrence of a 'carriage return' (13) or 'end of text' (3)
caused the skipping of the next character check, immediately
searching for it in the list of available characters.
If the next character was also 13 or 3, it led to incorrect
interpretation; however, if it was the last character in the
sequence, a crash occurred.

e50bf002de lottie: handle edge case for rounded rect
For rounded rectangles the roundness value should

r = min(r, max(size.x, size.y)/2)
rather than the previous method:
r = min(size.x/2, size.y/2, r)

also fix a potential paints corruption problems.

- Stroke Color
- Stroke Width
- Stroke Opacity
- Opacity
- Rotation
- Position
