cf09ba5abd common sw_engine: code refactoring 
Even though this enlarges the binary size by 300bytes,
use the array instead of individual implementations for better maintenance.

d520da2db8 sw_engine image: optimized image rendering. 
Applied the fast-track routine for axis-aligned images.
This helps to remove outline generation if no clips.

362d2dfd0f sw_engine: refactoring 
The rasterization region was rearranged in the case of fastTrack,
but its validation and boundaries weren't check, causing segf in some
cases. Fixed.

bba162b604 sw_engine: fix MSVC compatibility problem. 
clz (count leading zero) is builtin function
that is not available in MSVC.

This patch replace clz for MSVC env.

Thanks @fire for pointing out this.

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.

ee1522a446 sw_engine math: fix regression bug. 
There is 1 pixel misaligned issue observed.
Found out transform() increases 0.5 pt always.

This transform() logic was broken by this change - e00f948705
and now recorvered to origin.

04c6295974 code refactoring 
remove unnecessary condition.
implementation won't be included multiple times not like headers.

Thus this condition is unnecessary.

it could lose remarkable value that occur stroking jiggling.

ffa4a7248b code refactoring 
Now, stabilizing is pretty enough.

Remove assert code so that we never abort process in any cases.
This also reduce the binary size.
