TVG Loader/Saver: tvg loader introduced 
This patch introduces tvg loader module for loading .tvg binary files.
This allows to load and reuse pregenerated scene.

tvg file format:
.tvg is a binary file format designed for saving/restoring the scene content.
It allows to save scenes and reuse them in other apps or to restore state of
the application.

@Example:
   auto picture = tvg::Picture::gen();
   picture->load(EXAMPLE_DIR"/tvg_file.tvg");
   canvas->push(move(picture));

@API Additions:
   Result paint(std::unique_ptr<Paint> paint) noexcept;

@Issue: Issue ticket is #375.

9b1356e7cb svg_loader: support stroke gradient 
The loader was ready to handle the gradient stroke, but there was no API to support
it when the loader was introduced. We've had this API for a while already, so
its call has been added.

3c19f2aaf5 svg_loader SceneBuilder: Remove incorrect calculation for radial gradient 
We are doing enough calculations in the parser if the unit is user space.
This causes the cx,cy coordinates of radial gradient to be calculated incorrectly.

bd566bdcb2 svg_loader SceneBuilder: Remove incorrect calculation for linear gradient

3911a252e2 svg_loader: the viewBox clipping composite layer added independently of the shapes bounds 
For now the bounding box of all the shapes was established and if it was larger
than the viewBox of the SVG, the clipping layer was added. The bounds api
returns the rectangle that encloses the shapes before any transformations.
So comparing it with the viewBox doesn't make sense. The comparison is removed
and the clipping layer is always added.

When a given value string is locale-independent, strtof has to be
replaced to custom function.
