font-patcher: Fix vertical alignment for non-Mono with ScaleGlyph

Browse source 
[why]
When creating a non-Mono font the vertical alignment does not observe a
possible ScaleGlyph group. Icons that should be far up (like the
degree-icon, which is ScaleGlyph-grouped together with a full height
symbol) end up centered vertically.

[how]
When the glyph is not scaled we just do not use the ScaleGlyph.
But that data is also needed for just shifting the glyph.
