I have just run through all of the regression tests, and with

assert self.Ok()

in GraphicsContextWx.__init__() removed, all works correctly on my Debian 
platform. 

My suspicion is that the problem is that wxGTK does not like to see calls to 
Ok() in derived constructors. Please let me know if this fixes the problem on 
your machine, John, as I now have no problems on the two platform available 
to me.

A few other notes:

- Save to TIFF does not work on my Linux box. wxGTK generates a 'not 
supported' error message.
- Text is not anti-aliased on my Linux box. I suspect that this is probably a 
GTK configuration issue on my box (other GTK 1.2 apps aren't anti-aliased 
either), but I'd love confirmation.
- Performance of double buffering is vastly better on wxGTK than on Win32. The 
performance under Linux is subjectively very similar to the old GDI-style 
version, but (as previously noted) much worse under Win32. I am not sure why 
this should be the case (my Linux box is much lower spec than the Win32 box, 
as well!)
