860068301a sw_engine raster: code refactoring. 
+ blending stages using macro magics.

I know this is a bit bad for code readibility but good for the maintanence

aff755aeb5 sw_engine texmap: introduced texture mapping polygon drawing. 
Introduced the texture-mapping algorithm for the image-scaler.
With this approach, we can support any arbitrary forms of the transformed shapes
while appling the scale factors - x/y separately.

Also this is more efficient when the transformed image is far from the rectangular form
because our current normal image rasterizer based on the given drawing region whereas
our new approach is span-based.

Thus, we applied this mechanism only for the transformed images.

c9377708a9 sw_engine image: ++optimization 
apply fast track to fast up the image rasterization.

only shifted image doesn't need to have the matrix-transform computation,
we can avoid it by just shifting offset xy by simple caculating.

1527f70221 sw_engine raster: allow image interpolation by increasing tolerance. 
current image interpolation method is a bit awkward,
because xy scale different scale factor is not allowed.

we must improve the algorithm,

but now considering floating point precision,
we allow the interpolation by less ratio floating fraction.

To preserve the naming convention function '_rasterTranslucentImageRle'
is reanmed to '_translucentImageRle'. The '_rasterTranslucentImageRle'
function is though created - it checks the composition method and calls
the corresponding function. Missing functions are marked, but not implemented
(separate commit).

479cea74cc common: Unmultiplicated colorspace 
This patch introduces _STRAIGHT colorspaces (ABGR8888_STRAIGHT and
ARGB8888_STRAIGHT) whose colors are un-alpha-premultiplied. Unmultiplicated
colors are especially needed for wasm thorvg loader and svg2png / tvg2png.
Only C version now.
