Neutral buttons are 1px larger in all directions due to outsize border https://www.dropbox.com/s/w0t83ajadxf2a1j/Screenshot%202014-03-05%2014.36.31.png
Ryan Kaldari and I were discussing earlier that it might work to have a transparent 1px border on the other types.
Change 117107 had a related patch set uploaded by Mattflaschen: Make .mw-ui-button height the same for all buttons https://gerrit.wikimedia.org/r/117107
Created attachment 14767 [details] Screenshot showing minor bevel issue with patch
Merged.
