Vertical text positioning

[SimonN]

Lix 0.9.39.

Text on buttons is not vertically centered. It's either okay or too high; maybe rarely, it's also too low. This bug manifests differently at different resolutions:

• 1280x800: Text is slightly too high.
• 1280x1000: Text is much too high.

Expected: Assuming the text were ALL CAPS, the text should be vertically centered on the button. I.e., the top of the capital A should be the same distance from the top of the button as the bottom of that capital A is from the bottom of the button.

Fonts have several different height lines that run horizontally across text: The top of lowercase f, top of a capital A, top of lowercase e, ..., are all different. I should find a source for graphic design 101 to cite. :-)
