OverlayTypes float 15px higher than they should, except walls/rocks/tib...

The drawing center of overlays is inconsistent based on what category they fall into, but all of them should be displayed the same. just like terrain the center of the canvas should be on the center of the cell, not drawn like a building where it's the top corner of the cell.

Obviously I don't know how this is coded, whether there's an override routine or offset applied selectively, but it makes previewing (some) railroad tracks and non-rock debris difficult.

There should be three or more situations for drawing coordinates of Overlays, which are actually very complex, including those within the grid like buildings (such as GAWALL NAWALL GAFWLL) and those at the center point (such as Terrain), which can be troublesome to solve

In the old FA2, rocks were also shifted high, so this was "fixed" for some categories of overlay explicitly, when it should be the default behaviour for ALL overlays, except walls I think...
