d9bbd433e8 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.

0a16152d75 api: renamed the composite with mask. 
Since we've separated ClipPath and Masking,
Masking now has a distinct and independent purpose.

API Modification:
 - enum class CompositeMethod -> enum class MaskMethod
 - Result Paint::composite(std::unique_ptr<Paint> target, CompositeMethod method) -> Result Paint::mask(std::unique_ptr<Paint> target, MaskMethod method)
 - CompositeMethod Paint::mask(const Paint** target) const -> MaskMethod Paint::mask(const Paint** target) const

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.

d7ab592fb9 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.
