[Mesa-dev] [PATCH 7/8] DRI2: support generic swap events
Jesse Barnes

Tue May 3 10:59:20 PDT 2011
Send the new generic swap event type if the client supports it. This
means checking the client's DRI2 proto version at connect time and then
constructing a new generic event at swap complete time. To track the
client version, we need to add a new DRI2 client private type and track
it for the lifetime of the client.
