Julian Smart dfad059924 Removed DrawOpenSpline since it doesn't seem to be needed, with required changes
in all ports. Added Motif wxFileDialog. Added wxPostScriptModule and removed
PostScript init in app.cpp. Also removed wxMessageBox function from
generic implementation. Windows release .exes are now smaller (< 300K for minimal.exe).
Some OGL updates. __try -> try in MSW main.cpp. BC++ 5 fixes.
