With GLX_SWAP_COPY_OML and GLX_SWAP_EXCHANGE_OML it may happen in situations

haven't yet allocated and initialized a new back buffer because there was
no GL rendering in between.
Make sure that we have a back buffer in those situations.

Is 0 a valid value for the back_format field? If not, the
have_back_format field is redundant.
I'll see if I can eliminate that field.
