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.
