Hmmm...
I've tried both explicitly sending the initial size in any of the following
ways:
1) widget.gl = wx.wxGLCanvas(widgets.test, wx.wxID_ANY,
wx.wxDefaultPosition, wx.wxSize(200, 200), wx.wxFULL_REPAINT_ON_RESIZE)
2) widget.gl = wx.wxGLCanvas(widgets.test, wx.wxID_ANY,
wx.wxDefaultPosition, wx.wxDefaultSize, 3) wx.wxFULL_REPAINT_ON_RESIZE)
3) widget.gl:SetClientSize(wx.wxSize(200, 200))
1 and 3 report the correct size with widget:GetClientSize(), while 2 reports
(0, 0).
How none of these have any visual effect - the widget remains invisible.
