792b6a786d sw_engine: fix linear grad issue 
The restriction of the 'length' of a linear gradient
to values greater than FLT_EPSILON was causing rendering
issues in cases where it was a valid gradient with well
defined dx and dy values.

ba3d2b77a1 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.

- Fill Opacity
- Stroke Color
- Stroke Width
- Stroke Opacity
- Opacity
- Rotation
- Position
- Scale
