Re: [Plplot-devel] Screen coordinates to data coordinates withwxWidgets driver

Okay Alan, will do. I was just a bit worried that there might be a reason why pltranslatecursor had never been documented or propagated to other bindings.

Sure.  There won't be a freeze on such merges to master for quite some
time so go ahead.  Please also include a test that exercises your
changes.  Would examples/c++/wxPLplotDemo.cpp be suitable for such a
test?
