1d4db59a25 common: revise the identifier() implementation 
Migrate the id property to the base class internals
so that pimpl classes could access the data easier.

This is a sort of prerequisite change for the coming texmap anti-aliasing.

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.

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.
Change the type to fix warnings and potential problems
that occur in conversion between int16_t and uint32_t.

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...

4485db4f15 svg_loader: a function to establish shapes boundries without a stroke introduced 
To handle the objectBoundingBox units, the shape's boundaries have to be known.
According to the SVG standard, a stroke shouldn't be taken into account. Since
the bounds() api uses the shape's stroke information, a new function is introduced,
that compensates this and returns boundaries without any strokes.

bd7c19a592 svg_loader: struct used to pass 1 args instead of 4 of them 
The Box struct is introduced to replace the four functions
args: vx, vy, vw, vh, so all of them can be passed at once.

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.
