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.

d4c15dcf66 common: nothing was rendered after an empty masked node came across 
The problem was observed for empty masked scenes (except the fastTrack
cases). Solved by imimediate returning from the func without passing 'false'
as its result.

f887edf562 common paint: fix the wrong fast track logic. 
There was a missing sorting between the left-top & right-bottom corner.
that results in the negative values of the viewport...

Now fixed it.

+ refactored to use math functions...
+ still it's a buggy, sometimes no draw at 90' in stress. don't know reason. :(

baab43aff2 tvg_saver TvgBinInterpreter: prevent misaligned memory access 
When parsing a binary stored as a char type,
interpreter can access the misaligned memory while accessing it with a pointer.
To prevent that, pass the array copied to memcpy as tvg Object.

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.
