Yep, that seems sensible to me, too. Will do that.

Also, I will probably get rid of the ConsoleOnly thing, and instead call
EnableHeadlessMode() in gengal and test IsHeadlessModeEnabled in SVMain().
(This will affect only OS X, as it is only on OS X that ImplSVMainHook()
can return true.)

BTW, despite the ConsoleOnly thing, gengal was still crashing on OS X when
running with no access to the window system. That was because the [NSScreen
screens] call in AquaSalGraphics::initResolution() naturally returned an
empty NSArray, but the code anyway tried to get the 0th object of it. I
fixed that today. Will push together with the other changes mentioned above
once I have done some double-checking.
