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 ColorStop offset < 0 and > 1 should be treated as 0 and 1 respectively.
The offset value < than the previous offset value should be replaced
by the previous value - without this change segfault occurred.
Validating the APIs parameters values is the user responsibility.
