ok, I start to understand : you want to switch between the 'old' and
'cairo' code at runtime in a wxDC instance. I see that we cannot do that
now.

I don't think the performance hits of another indirection would really
be a problem when dealing with graphics code, as we are giving
high-level commands.

If you find a way to reuse wxGCDC implementation I think we would
benefit from a single implementation point for a cairo feature, but of
course, that's just my view ...

Best,

Stefan
