This event is generated when the buffers the client had
requested for 'drawable' (with DRI2GetBuffers or
DRI2GetBuffersWithFormat) become inappropriate because they
don't match the drawable dimensions anymore, or a buffer swap
has been performed.
Note that the server is only required to warn the client once
about this condition, until the client takes care of bringing
them back up-to-date with another GetBuffers request.
