Crash on Raspberry Pi 3 B+

[birktj]

The current version of glutin seems to crash on Raspbian on the Raspberry Pi 3 B+. The error message is CreationErrors([NoAvailablePixelFormat, OsError("Couldn't find any available vsync extension")]). The issue can be replicated by trying to execute the window example on the raspberry. Older versions of glutin (eg. 0.21) does not have this problem, but I have not done a proper bisection to see where the problem appears. Not that despite the error message I have tried to explicitly disable vsync by using with_vsync(false).
