-**   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.

+** 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.
