9ce784751c lottie: correct the array reserved size
The color input will contain at least colorStops.count * 4
elements (not including alpha). Since the alpha offset values
don't have to much colorStops, estimation is used.

90e7a50c8e 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.

d9326921fa lottie: fix repeater order
Assigning numbers 1 or 2 to a bool always
resulted in true. Now fixed and repeated
shapes are drawn in the proper order.
If the repeater had no elements, iterating
shapes from the end would result in a segf.
This issue is now fixed.

b812277a06 lottie: add 'tp' tag support
So far it hasn't been possible to specify
a matte layer - by default, it was the layer
above the calling layer. The 'tp' tag support
has been introduced, enabling referencing any
layer by its index.
In cases where the layer referencing the matte
was the first one, a segmentation fault was
observed. This issue has now been resolved.

027e0fd6f0 lottie/expressions: enhance stability
When the system fails to interpret the expression code,
it forcibly disables the feature per property.

This improvement enhances stability and performance
by avoiding reckless attempts to interpret JavaScript code.

When we confirm the full stability with expressions,
we can revert this code.
