Merge most of the horizontalBar controller into the bar one but also fix stack groups and bar positioning when scales are stacked or when a min and/or max tick values are explicitly defined. Note that this is a breaking change for derived controllers that rely on the following removed methods: `calculateBarBase`, `calculateBarX`, `calculateBarY`, `calculateBarWidth` and `calculateBarHeight`.
