e50bf002de lottie: handle edge case for rounded rect
For rounded rectangles the roundness value should
be determined using to the formula:
r = min(r, max(size.x, size.y)/2)
rather than the previous method:
r = min(size.x/2, size.y/2, r)

c20ecbcc58 lottie: introduced LottieRenderPooler
LottieRenderPooler is designed to manages rendering
instances(paints) efficiently through a simple pooling
mechanism to resuse among the animations

This replaces the previous individusal paints implemenations
among solidfill, precomp vierport and pictures,
also fix a potential paints corruption problems.

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.

7b9bebe1de lottie: repeater transformation fix
In the case of a transformation (denoted as T1)
appearing after the repeater, but at the same
level of nesting, the objects to which the repeater
is applied should not consider T1. However,
the transformation of the repeater itself should
take T1 into account.
Also, it is possible to have several consecutive
repeaters, and all of them should be taken into
account. Until now, the last one was overwriting
the previous one.

1ee79a6c2a 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.
