The opacity value is interpolated as are all color channels.
It's similar to the reverted commit ac95433, but with two slight changes
(alpha_blend was missing in the ctable init and 'a' was used in an if
statement instead of 'a2').
In the fillFetchLinear function the offset parameter was removed.
The destination address may be shifted directly in the dst parameter,
it doesn't need to be passed separately.
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.

Renamed internal interfaces.
We need both blender & compositor interfaces.
Renamed SwCompositor -> SwBlender which is for pixel joining methods.
Added (SwCompositor, Compositor) which is designed for compositing images.
we should avoid code insertion during file dependencies,
such as #include "xxx.h" which has implementations.
This could increase binary size, we can avoid it as possible.
Current patch improves binary size like this:
From: file(2059008) = text(120360) data(8096) bss(80) dec(128536)
To : file(1921832) = text(118429) data(7872) bss(56) dec(126357)
More additional patches will come in to optmize binary size.
warning: absolute value function 'fabsf' given an argument of type 'double' but has parameter of type 'float' which may cause truncation of value [-Wabsolute-value]
remove unnecessary condition.
implementation won't be included multiple times not like headers.
Thus this condition is unnecessary.

Actually Dali rendering system requires abgr8888.
We could add more colorspaces if it's necessary.

Now, stabilizing is pretty enough.
Remove assert code so that we never abort process in any cases.
This also reduce the binary size.

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.

Some user have no idea of premultiplied alpha concept,
We suggest more user-friendly interfaces so that they don't confuse it.
Now, this pre-multipying is acommplished by backend engines.

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
Current patch supports only for raster solid color

there are unnecessary partial spans generated in orthogonal rectangle.
we can merge those partial spans to others if they are on the same scanline...

memset() is more than 10x faster than manual loop.
Thus we replace it to manipulate buffer pixels.

this interface is designed for user-defined arbitrary affine-transform paints.
required by svg loader.
