Supporting wxDC in the GAL is a curious expenditure of time.  Did you see the discussion
about class PAINTER ?


class PAINTER is a *compile time* implementation abstraction.

So I don't see putting wxDC behind the GAL useful when when goes to implement the wxDC
version of a PAINTER.

The goal of PAINTER is to minimize propagation of any graphics API, GAL or otherwise.

Propagation is that what you spread around, like planting seeds all over the place.
