Summary: glcanvas gtk_widget_set_colormap assertion

Initial Comment:
Hello.

When use wxGlCanvas with wxGTK build, I have a gtk assertion :
Gtk-CRITICAL **: gtk_widget_set_colormap: assertion `!GTK_WIDGET_REALIZED (widget)' failed

The alone use of gtk_widget_set_colormap function (for wxGTK2 build) is src/gtk/glcanvas.cpp:339.
In gtk documentation [1], it is specified that this function must be called before the widget is realized however in the wxGLCanvas::Create function, it calls wxWindow::Create (l325) which (src/gtk/window.cpp:2394) shows it.

When I suppress gtk_widget_set_colormap call, assertion is not shoewd anymore and nothing is affected.

Regards
Emilien KIA
