332012dd6b loader svg: displaying SVG images without the specified viewBox attribute 
If no viewBox attribute is given, the height and width attributes are used
to establish the viewBox size. However, this information was not available
inside the scene builder, even though it was needed.

0f9d3ff6e9 examples: ignoring pictures other than svgs in Stress.cpp 
The picture->size() function does not work for raw/png pictures.
As a consequence enabling both, the svg and png file loaders,
resulted in the unintended behavior of the example.

5c9016158e loader svg: fix composition(mask/clip) issue. 
composition target missed transform of its source.

That brings incorrect composition area.

30ee03002b sw_engine: fixing stroke gradient 
Instead of checking the stroke's fill, the shape's fill was checked.
As a result the improper rastering function was called (or none).

35fdc9a278 loaders svg: set default color for composition paint. 
not only clippath but alpha compositions might also have any valid color.

903df3da6a loaders svg: prevent composition setting if the result shape is invalid. 
Current loader could return invalid shapes -default, from _appendShape()-
by a certain interpretation result,

Though it's a wrong or exception case, we can prevent worse case by avoiding it.

f1fe36d8f6 common sw_engine: optimize single rectangle ClipPath. 
If ClipPath is a singular rectangle,
we don't need to apply this to all children nodes to adjust rle span regions.

Rather than its regular sequence,
we can adjust render region as merging viewport that is introduced internally,

All in all,
If a Paint has a single ClipPath that is Rectangle,
it sets viewport with Rectangle area that viewport is applied to
raster engine to cut off the rendering boundary.

In the normal case it brings trivial effects.
but when use SVGs which has a viewbox, it could increase the performance
up to 10% (profiled with 200 svgs rendering at the same time)

Note that, this won't be applied if the Paint has affine or rotation transform.
