641fe5b544 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.

ac7177127a lottie: ++optimization with object culling 
More precisely, culling the render objects by
determining if the group has no renderable objects.

Additionally, check opacity to quickly return

1131695ce4 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.

c922eb9d2d svg_loader: Fix incorrect stack.pop() call in loader 
loader->stack.pop() at line 3271 is called to remove
the defs node added to the stack due to nested graphics elements.
However, it is called in an inappropriate situation and the loader's node tree is damaged.
Fixes an error where the close tag is recognized as a `line` of the graphics tag when it is `linearGradient`.
ex)
```
    <defs id="def">
        <linearGradient x1="1" y1="2" x2="3" y2="4" id="l"/>
        </linearGradient>
        <rect x="10" y="10" width="10" height="10"  fill="blue" id="r2"/>
    </defs>
```
