tvg_saver: implementation of the Saver class 
The Saver class enables to save any Paint object (Scene, Shape, Picture)
in a binary file. To read the file the tvg loader should be used.
To save a paint a new API was introduced - tvg::Saver::save.

sw_engine: preventing a double application of the opacity (#540) 
For filled and stroked shapes with a gradient, the opacity
was applied during the composition and during the ctable update.
To prevent this, in case the composition occured, ctable
is updated with the opacity = 255.

0435f29f11 jpg_loader: introduced jpg decode using libjpeg-turbo 
This patch introduces a jpg loader.
For decoding the image, libjpeg-turbo library is used. Library was found to be

a40d3f6fd7 sw_engine: stop-opacity value should be interpolated between stops 
The opacity value is interpolated as are all color channels.
It's similar to the reverted commit ac95433, but with two slight changes
(alpha_blend was missing in the ctable init and 'a' was used in an if
statement instead of 'a2').

c31156e737 sw_engine renderer: fix a broken composition bug 
tvg sw_engine tries to skip composition as far as its doable,
it tries composition only if the translucent shape with stroking is there.

There has been a condition bug that composition is applied unnecessarily
even if stroking is disabled. This resulted in broken blending
at gradient filling since it applied alpha values multiple times.

96d6b47a64 common: PaintType enum changed to identifier in Paint class 
The PaintType enum was used to set the paint type in the internal Paint
implementation. This solution is switched to an identifier with id() getter,
so that the information about the type can be reached from outside the Paint.

286f700305 svg_loader: handling the ColorStop offset values

The offset value < than the previous offset value should be replaced
by the previous value - without this change segfault occurred.

88a85c68fa loader_mgr: FileTypes order changed 
FileType order was changed in tvgLoaderMgr.h to move Tvg at the beginning.

When raw data loading [LoaderMgr::loader(data, size)], loaders are tried
one by one (in order according to the FileType enum) until the correct loader
is found.
When using EFL and load edj, multiple loader(data, size) with tvg data may be
called. This change should improve performance in that case.
