I think that getting automatic OpenGL detection and recovery working for
5.0 might be ambitious.
Maybe Chris can detail what the next steps are for his approach there, but
in case we want to push that to a later release, here's what I propose:

1) Rename the View menu options based on my proposal "Legacy", "Modern
(Accelerated)", "Modern (Fallback)"
2) Change PCB_BASE_FRAME::SwitchCanvas to save the canvas config value
after calling UseGalCanvas() rather than before.
3) Show a first-run dialog like the mockup in my earlier email, IF canvas
is not OpenGL and the dialog has not been shown before
44) If user clicks "yes" in the first run dialog, then:
    (a) set the config value to prevent the dialog from showing again,
    (b) Set the canvas config setting to Cairo (but don't switch the GAL to
Cairo), then
    (c) switch to OpenGL canvas using SwitchCanvas()

That way, if the app crashes in step 4c, it should come back up as Cairo on
the next launch (assuming we crash right away when trying to set up the
canvas)

Any concerns with the above?
