Fix FS#12951: The icons could be a pixel to far down.

Since eec89a9 icons have been centered using same calculation as for fonts.
In edge cases this is visually different from before and didn't align
well to the font's baseline. Revert to the old calculation just for centering
icons to fix.

A proper aligorithm would take the baseline into account but this has
worked sufficiently well for us (fix this if needed)
