* svg_loader: preserveAspectRatio attrib handled according to the svg standard
* svg_loader: symbol fixed
The correct width/height values used in the _useBuildHelper function.
Bug was propageted while the preserveAspectRatio attrib was handled,
now fixed.
* svg_loader: refactoring code regarding the preserveAspectRatio attrib
To avoid copy/paste a new function is introduced to handle the proper
scaling.
* svg_loader: initialize the svg loader members
The 'align' and 'meetOrSlice' svg loader members were not initialized.
* svg_loader: resize function forces any transformation
The resize function is called after the svg image is read and scaled
taking into account the proper preserveAspectRatio value. While resizing
the preserveAspectRatio isn't checked any more and the image can be
freely transformed.
If no viewBox attribute is given, the height and width attributes are used
to establish the viewBox size. However, this information was not available
inside the scene builder, even though it was needed.
* common Picture : Introduce Picture's size setter, getter APIs
If picture or file loaded by picture has an explicit Size(width, height),
it is transformed to fit the size.
we should avoid code insertion during file dependencies,
such as #include "xxx.h" which has implementations.
This could increase binary size, we can avoid it as possible.
Current patch improves binary size like this:
From: file(2059008) = text(120360) data(8096) bss(80) dec(128536)
To : file(1921832) = text(118429) data(7872) bss(56) dec(126357)
More additional patches will come in to optmize binary size.
