keyboard) uses its own OpenGL ES context but doesn't restore the
previous one when it's done. This is a workaround to make sure the
expected SDL-created OpenGL ES context is active after the OS is
finished running its own code for the frame. If this isn't done, the
app may crash or have other nasty symptoms when Dictation is used.
