Since the color space is set at the time of specifying the target buffer of the canvas,
there is no way to know the color space when the picture is loaded.
So, check the color space applied to SwCanvas at the time of reload()
and change the color space.
There is an issue of BGR color space support for each loader.
The external_jpg loader resets the TJPF color space and calls read() to get a new buffer.
In the case of external_png, we need to change the color value directly
because it have to start over from begin_read_*.
This solution can affect performance as much as it access again image buffer
that have already been `read()` done. However, this only happens once.
* 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.
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

This reverts commit cd5116b053.
Ah this breaks the Stress example due to Picture::duplicate() is not available...
Need to consider and come back again.
* common: added colorSpace() function
This patch introduces colorSpace() function for SW and GL engine.
* infra: change LoadModule:read() into LoadModule:read(uint32_t colorspace)
This patch changes LoadModule:read() into LoadModule:read(uint32_t colorspace)
* picture: implement passing colorspace into loader
This patch implements passing colorspace into loaders.
Loader->read is now called on the first update.
* external_jpg_loader: support colorspaces
* external_png_loader: support colorspaces
Bitmap based pictures doesn't need the viewbox,
LoaderModule should delegate the viewbox to the derived classes which
having vector-based image loaders such as svg, tvg.
In that case, paint resizing can be performed by the loaders by own
policy.
replace from Scene to Paint at the internal interface.
Picture doesn't need to know the returned Node type.
base class, Paint is enough to in the data passing.
