- * DBE MI Procedure: miDbeWinPrivDelete

- *

- * Description:

- *

- *     This is the MI function for deleting the dbeWindowPrivResType resource.

- *     This function is invoked indirectly by calling FreeResource() to free

- *     the resources associated with a DBE buffer ID.  There are 5 ways that

- *     miDbeWinPrivDelete() can be called by FreeResource().  They are:

- *

- *     - A DBE window is destroyed, in which case the DbeDestroyWindow()

- *       wrapper is invoked.  The wrapper calls FreeResource() for all DBE

- *       buffer IDs.

- *

- *     - miDbeAllocBackBufferName() calls FreeResource() to clean up resources

- *       after a buffer allocation failure.

- *

- *     - The PositionWindow wrapper, miDbePositionWindow(), calls

- *       FreeResource() when it fails to create buffers of the new size.

- *       FreeResource() is called for all DBE buffer IDs.

- *

- *     - FreeClientResources() calls FreeResource() when a client dies or the

- *       the server resets.

- *

- *     When FreeResource() is called for a DBE buffer ID, the delete function

- *     for the only other type of DBE resource, dbeDrawableResType, is also

- *     invoked.  This delete function (DbeDrawableDelete) is a NOOP to make

- *     resource deletion easier.  It is not guaranteed which delete function is

- *     called first.  Hence, we will let miDbeWinPrivDelete() free all DBE

- *     resources.

- *     

- *     This function deletes/frees the following stuff associated with

- *     the window private:

- *

- *     - the ID node in the ID list representing the passed in ID.

- *

- *     In addition, pDbeWindowPriv->nBufferIDs is decremented.

- *

- *     If this function is called for the last/only buffer ID for a window,

- *     these are additionally deleted/freed:

- *

- *     - the front and back pixmaps

- *     - the window priv itself

+ * DBE MI Procedure: miDbeWinPrivDelete
+ *
+ * Description:
+ *
+ *     This is the MI function for deleting the dbeWindowPrivResType resource.
+ *     This function is invoked indirectly by calling FreeResource() to free
+ *     the resources associated with a DBE buffer ID.  There are 5 ways that
+ *     miDbeWinPrivDelete() can be called by FreeResource().  They are:
+ *
+ *     - A DBE window is destroyed, in which case the DbeDestroyWindow()
+ *       wrapper is invoked.  The wrapper calls FreeResource() for all DBE
+ *       buffer IDs.
+ *
+ *     - miDbeAllocBackBufferName() calls FreeResource() to clean up resources
+ *       after a buffer allocation failure.
+ *
+ *     - The PositionWindow wrapper, miDbePositionWindow(), calls
+ *       FreeResource() when it fails to create buffers of the new size.
+ *       FreeResource() is called for all DBE buffer IDs.
+ *
+ *     - FreeClientResources() calls FreeResource() when a client dies or the
+ *       the server resets.
+ *
+ *     When FreeResource() is called for a DBE buffer ID, the delete function
+ *     for the only other type of DBE resource, dbeDrawableResType, is also
+ *     invoked.  This delete function (DbeDrawableDelete) is a NOOP to make
+ *     resource deletion easier.  It is not guaranteed which delete function is
+ *     called first.  Hence, we will let miDbeWinPrivDelete() free all DBE
+ *     resources.
+ *     
+ *     This function deletes/frees the following stuff associated with
+ *     the window private:
+ *
+ *     - the ID node in the ID list representing the passed in ID.
+ *
+ *     In addition, pDbeWindowPriv->nBufferIDs is decremented.
+ *
+ *     If this function is called for the last/only buffer ID for a window,
+ *     these are additionally deleted/freed:
+ *
+ *     - the front and back pixmaps
+ *     - the window priv itself
