05fefcf61f sw_engine raster: ++safety of the scaled image rasterization 
Prevent out of buffer boundary access.

45132a7051 sw_engine raster: improve the transformed rle image rasterizer. 
replace the transformed rle rgba image with the texmap raster.

this patch removes the several scattered transformed image rasterizer,
reuse the unified one texmap method instead.

yay, it's much clean and optimal.

4cdf648e14 sw_engine image: support non-premultiplied alpha images. 
Previously, translucent png images are not displayed properly
due to alpha channels premultiplication.

This patch implements that missing part to support it properly
by introducing the Surface data between canvas engine & rasterizer

e7b7705875 sw_engine raster: remove unnecessary functions. 
These alpha/inverse alpha blender table is not useful so far,
we remove them since it just decrease the performance by by-pass addressing.

c0cd645bb5 sw_engine raster: fix the regression bug of the image simple scaling rendering. 
Gave up the optimization this logic.

It brings too many digressed code, not good for maintenance...

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.
