manualSizePane is an exposed flow-through method allowing extra code when pane is 'manually resized'

@param {(string|Object)}	evt_or_pane				The pane being resized
@param {number}			size					The *desired* new size for this pane - will be validated
@param {boolean=}			[skipCallback=false]	Should the onresize callback be run?
@param {boolean=}			[noAnimation=false]
@param {boolean=}			[force=false]			Force resizing even if does not seem necessary
