Addendum to #90 Should be on xml resLoc + modid basis Allow for all UIs: - override gui-scale additively, eg. vanilla settings is 2x, but user would like to have 4x Allow for single primary resizable element: - override gui size additively, eg. xml size is 320x240, but user would like to have 320x480 - override gui size anchor, ie. xml size (now) or screen size (fullscreen window type without scaling) - effectively enabling UI to follow screen resolution - should be automatic or UIs having only one resizable element at root view (list or zoomdrag only?)
