AFAICT the reason this code doesn't use RETURN_EGL_ERROR like
everything else is because it doesn't lock the display. Which is
extremely wrong, since we definitely depend on it not going away from
under us later! Fixed in v2.

Done in v2.

There's a bunch of places where we don't check that...

Nope. You're allowed to set the disposition for multiple error levels
in a single call to DebugMessageControl, so you need to validate them
all.

Meh. I factored out the valid-debug-level check to a helper, at which
point you can't really use a switch. Redone as a do-while so I could
use break to bail out of the success conditions.
