    This adds a canvas member variable and the necessary logic so that
    loading and saving zoom can be enabled and disabled in a canvas-local
    fashion via `declare -zoom`, overriding the global sys_zoom flag.
    An update of the declare help patch is included. It adds a new
    Patch_local subpatch which explains the new option.
