[PATCH] Remember drawable ID used to find damage target for use in events. Bug 5730.

[Keith Packard]

Using Composite, window pixmaps are given names in the client resource
namespace and yet may not have any XID recorded in the drawable
structure. As such, we need to remember the XID used to lookup the
pixmap in the resource database so that we can report the correct XID
back to the client in damage events.
