df64a7b0dc sw_engine raster: fix a crash at the texmap clipping. 
Handle correctly duplicated spans from the multiple y span data.

Previous logic only expected the one single y span data from the rle.
However rle might have multiple y span data if the anti-aliasing is applied.

This patch also removed the bad design of the common engine
which handles the anti-alising option to ignore the anti-aliasing rle generation.

Just realized, it's difficult to control that condition due to scene-composition.

e258a2a662 sw_engine texmap: implemented fast span-edge anti-aliasing 
This Anti-Aliasing mechanism is originated from Hermet Park's idea.

c326b6ac3e sw_engine SwShape: Prevent null access 
strokeOutline returned strokeExportOutline() is the address of mpool->strokeOutline[idx].
Assuming this value is null, mpoolRetStrokeOutline on line 617 will access mpool->strokeOutline[idx].
Logically, the logic of the mpool* functions does not occur in this case.

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

d8797092b5 sw_engine SwCommon: Change spans's x,y value type 
The x and y of spans cannot be negative
because they are specified as coordinates inside the buffer.

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.
