+** File:
+**
+** xvmain.c --- Xv server extension main device independent module.
+**
+** Author:
+**
+** David Carver (Digital Workstation Engineering/Project Athena)
+**
+** Revisions:
+**
+** 04.09.91 Carver
+** - change: stop video always generates an event even when video
+** wasn't active
+**
+** 29.08.91 Carver
+** - change: unrealizing windows no longer preempts video
+**
+** 11.06.91 Carver
+** - changed SetPortControl to SetPortAttribute
+** - changed GetPortControl to GetPortAttribute
+** - changed QueryBestSize
+**
+** 28.05.91 Carver
+** - fixed Put and Get requests to not preempt operations to same drawable
+**
+** 15.05.91 Carver
+** - version 2.0 upgrade
+**
+** 19.03.91 Carver
+** - fixed Put and Get requests to honor grabbed ports.
+** - fixed Video requests to update di structure with new drawable, and
+** client after calling ddx.
+**
+** 24.01.91 Carver
+** - version 1.4 upgrade
+**
+** Notes:
+**
+** Port structures reference client structures in a two different
+** ways: when grabs, or video is active. Each reference is encoded
+** as fake client resources and thus when the client is goes away so
+** does the reference (it is zeroed). No other action is taken, so
+** video doesn't necessarily stop. It probably will as a result of
+** other resources going away, but if a client starts video using
+** none of its own resources, then the video will continue to play
+** after the client disappears.
