Specifically, “mechanically C++-ified” means taking Cairo as-is and transforming it with a one-page list of mechanical changes such as turning _create functions into constructors, (mystruct*, int length) function parameters to vector<struct>& parameters, that sort of thing – the design and abstractions and functions are unchanged. This would also allow us to track Cairo as it evolves in the future, by continuing to reapply the same rules to new updates to Cairo.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>We know about Cairomm but it seems to have languished so we are focused on current Cairo as a starting point, even though it’s not C++ -- we believe Cairo itself it is very well written C (already in an OO style, already const-correct, etc.).<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>We want to make sure we’re doing this in the right way and with the group’s approval, so your feedback would be much appreciated.
