Hi,
I was updating my local dri2.xml based on the latest dri2proto.h [1]
and I noticed that the DRI2 event BufferSwapComplete is too long to fit
core protocol events.
The best I can calculate is
sizeof(xDRI2BufferSwapComplete) == 34
which disagrees with
#define sz_xDRI2BufferSwapComplete 32
I suppose if event_type would be a CARD8, it could fit where the padding
is now and the length discrepancy would be fixed.
Any comments?
