If you've got a proto version on both sides, you should just stick the
low 32 bits in place of the event type and pad fields, rather than
abusing. Yes, this requires two different structures in the X server,
but you need to do that anyways -- the event type has to shrink from 16
bits to 8 bits, moving it at the same time is not a problem.
Besides, this will make the xcb case really ugly as xcb doesn't hide the
protocol event structures from the application.
