Create resources on the back-end server. This function is called from dmxAttachScreen() via the dix layer's FindAllResources function. It walks all resources, compares them to the screen number passed in as n and calls the appropriate DMX function to create the associated resource on the back-end server.

Create window hierachy on back-end server. The window tree is created in a special order (bottom most subwindow first) so that the dmxCreateNonRootWindow() function does not need to recursively call itself to create each window's parents. This is required so that we have the opportunity to create each window's border and background pixmaps (where appropriate) before the window is created.

Destroy window hierachy on back-end server. To ensure that all XDestroyWindow() calls succeed, they must be performed in a bottom up order so that windows are not destroyed before their children.

Save the pixmap image only when there is not another screen with that pixmap from which the image can be read when the screen is reattached. To do this, we first try to find a pixmap on another screen corresponding to the one we are trying to save. If we find one, then we do not need to save the image data since during reattachment, the image data can be read from that other pixmap. However, if we do not find one, then we need to save the image data. The common case for these are for the default stipple and root tile.
