Removing the legacy canvas cannot be done until there is an acceptable
solution for users who do not have usable opengl on their systems.  The
Cairo canvas is not usable even on the fastest system I've have access
to.  Until either Cairo gets a significant speed boost, opengl becomes
usable on all platforms, or we port wxDC to GAL, it will have to stay.
