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

Thus this condition is unnecessary.

9d58643a6c sw_engine: fix loss of data when it's converting.
if SwCoord type is determined to 4byte,
it could lose remarkable value that occur stroking jiggling.

This fixes the issue.

06d8d06993 sw_engine: replace rgba8888 with abgr8888
Actually Dali rendering system requires abgr8888.

We could add more colorspaces if it's necessary.

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.

70b4703707 remove print/cout logs.
we need a comprehensive logging interface for this.

right now, leave as "LOG:" to replace later.

f4d1065d52 sw_engine: convert colorspace ARGB -> RGBA in default.
We can use RGBA colorspace rather ARGB for pixel data.
This would be better for many rendering system,
since it's more widely preferred than ARGB including opengl.

7289116227 remove std async usage.

4d72eeda15 sw_engine: revise scale transform logic.
Basically, stroke width size is linear,

engine couldn't apply scale factor from the matrix which contains 2 dimensional values.

Thus, we can apply it if the scale factor of x/y is identical.

Otherwise, we should transform every stroke points in the stroking process.
That scenario can be improved with another patch.

96477c0a24 sw_engine: revise outline transform
sw_engine simulates floating point by integer bit shifting,
it loses the accuracy while converting the number data.

This occurs the inacculated curve points result if it scales up very large size.

So we transform points before converting data in order to avoid losing the numbers less decimal point.

9e1ba8d2c0 sw_engine: introduce avx simd instruction
avx is the cutting edge method for intel & amd cpus simd instruction.
We are going to support this feature for the desktop environment (instead of sse)

You can turn on this with configuration something like this:

$meson . build -Dvectors=avx
