added a routine that draw non-transformed translucent image.
composition images will use this routine to draw faster.
Also added optimization point comments in raster image.
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.
Introduce RendererMethod::renderRegion() to return acutal drawing region info.
That is used by scene composition to composite actual partial drawing region
for better performance.
@Issues: 173
Move the prepare stage of shape & stroking composition stage to a separate function
this returns SwImage to use in composite stage.
Also clear partial region buffer since we know composition area.
* sw_engine raster: code refactoring & optimize code.
1. move the computation out of rolling if possible.
2. renamed internal variables & function prototypes.
Add RawLoader class that loads and display raw images,
and adds a Rasterizer for image data.
Image data can be loaded via picture.
Loaded image supports Composition, Transformation and Alpha blending.
New API
Result load(uint32_t* data, uint32_t width, uint32_t height, bool isCopy) noexcept;
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.
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.

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.

we can't control any threads count that could drop the performance.
remove async() and will come back with fine-tuned threading-pool.

these conversions are intented, we explicity use casting so that compiler doesn't
catch them anymore.

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

if the rectangle is not transformed, we don't need to use rle method.
we can directly raster pixels onto the bounding box.

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