sw_engine fill: fix wrong gradient transformation 
There transformation logic was not identical between shape & gradient

gradient transform was applied into center of gradient world,
while shape wasn't. So... we correct gradient transform metric to shape like.

Issue 180 example (#212) 
* examples: Added resize_cb to Capi example.

resize_cb in capi example is used to verify crash on reize described
in @180 issue.

* examples capi: Fixed file type from dos to unix.

Use the same code style as it is used in other examples.

f0ab7f4002 sw common: Fixed crash in rasterRGBA32 
Description:
Crash was observed in examples when composite object was used.
It was caused because __m256i object was used on non aligned
memory to 32bit. Algorithm in this function was changed to use
unaligned __m256i_u object. Code was also simplified.

6db7f85ffb common Scene: Fix translucent composition condition 
If a scene has another scene as a child and
the number of children is 1, the composition of the child does not work.
Therefore, fix that composition works as long as the number of children is not 0.

f1fd23cf32 common render: removed unnecessary assignments in update() fun 
The rotation part of the transformation matrix can be assigned,
it does not have to be multiplied by the identity matrix.
The values of e13 and e23 of the transformation matrix represents the translation,
so they don't need to be taken into account in the rotation part.

6a4598f706 infra coding_style: Add coding style check bot 
Add a bot that checks the coding style using cpplint
and reports the result as a review comment.

This feature refers to the repository where cpplint
and docker settings with github-action.
This action works whenever a PR is created and updated.

In cpplint, only the violation of ThorVG's coding style is reported
as a warning using several options.
whitespace/parens
whitespace/indent
whitespace/end_of_line
whitespace/blank_line

The bot will review all of the contents of all files in the current commit file list,
However, in the future, we will improve Bot to only review the changes.
