Add support for the 'Present' extension. [v3]
This makes updating the eyes nicely vblank synchronized.
v2:
Ensure extensions exist before calling query_version
These calls add calls to xcb_get_extension_data before calling
query_version calls, as those calls will mark the connection
with an error if made against an X server without the
extension present.
Suggested-by: Uli Schlachter <psychon@znc.in>
v3:
check the 'present' field in the return from
xcb_get_extension_data; the xcb_get_extension_data call will
always succeed (save for out of memory), the only way to tell
if the extension is supported in the target X server is to
test the 'present' field in the query extension reply value.
