LibGfx: Move vertically centered text down slightly based on baseline

To make slightly more aesthetically pleasing use of the vertical space,
we now move all vertically centered text lines down by half the amount
of space below the font's baseline.

This is probably not the "correct" way to do this, but it does make
things look nicer with some of our fonts already.
