u16F54 (and u16F66?) should sit on baseline at F position

[jvgaultney]

Currently u16F54 is top-aligned when at S position, but is centered in the box at F position. It should instead sit on the baseline at F position. Current position:

Should this positioning also be applied to u16F66?

This will require moving the outline lower and moving all the non-F/FR APs lower by the same amount.

Yes, both should sit on the baseline. One catch, however, is [lpo] wants 16F54 to be centred when following 16F61. See Issue #54 .

These two glyphs will now sit on the baseline at F position. All other positions are unaffected.

However that will undo #54 at F position for [lpo]. Do we need to do a special lookup just to give u16F61+u16F54/u16F61+u16F66 special F positioning just for [lpo]? And where should 54/66 be positioned for [lpo] when it's not after u16F61?

[cheuk879]

Special lookup would be appreciated. When not after u16F61, normal positioning applies (i.e., top-aligned at S, bottom-aligned at F).

Users have confirmed that this fix is working now. The special case of u16F61+ is a separate issue #54
