|

* 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
