wxSplitterWindow and wxGLCanvas resize in GTK

[philparsonage at hotmail.com]

Essentially, on resizing a wxGLCanvas by using a wxSplitterWindow, the
new part of the background is drawn in the background colour of my
wxGLCanvas, rather than being redrawn by the wxGLCanvas itself. It's
like the glViewport has been set wrong, even though in the OnSize of my
wxGLCanvas I set the glViewport to be the correct size.

This is fixed if I call Update() (and thererfore invalidate the
background) in my OnSize, but even then, I'm getting flashing as I
resize the entire application window. I don't see this behaviour in
MSW, only on GTK.

If you replace the splitter sample with the code I posted above, (and
add some gl libraries into the makefile) it should build, and try
resizing the splitter window and the application. You should see what I
mean then. The example I've posted above isn't that long, it's only
turned into quoting by one line!

Thanks for your help,
Phil
