From the Present extension specification:
An event context is associated with a specific window; using
an existing event context with a different window generates
a Match error.
If eventContext specifies an existing event context, then if
eventMask is empty, PresentSelectInput deletes the specified
context, otherwise the specified event context is changed to
select a different set of events.
If eventContext is an unused XID, then if eventMask is empty
no operation is performed. Otherwise, a new event context is
created selecting the specified events.
Without this change, there's no way for a client to explicitly change
or destroy an existing event mask entry. Trying to do so as specified
above would just result in a protocol error.
v2: (Keith Packard)
* Use dixLookupResourceByType instead of walking window_priv->events
* Return BadMatch if the existing event context is associated with a
different window or client
* Call LEGAL_NEW_RESOURCE again when creating a new event context
* Drop invalid "leak fix"

Present didn't provide the 'kind' argument to the
present_complete_notify hook that GLX uses to construct
GLX_BufferSwapComplete events, so GLX was reporting events for
PresentCompleteKindMSC notifications, which resulted in duplicate
GLX_BufferSwapComplete events and crashes in clutter.

This lets us stop using the 'pointer' typedef in Xdefs.h as 'pointer'
is used throughout the X server for other things, and having duplicate
names generates compiler warnings.
