Test failures on Windows XP Japanese due to fonts selection differences

[Austin Lund]

There are a number of test failures due to hardcoded sizes in test
which fail for particular platforms, e.g.

http://test.winehq.org/data/6e89a61446088dbe029913896dfae467bb8d37a1/xp_wtb-...

It seems the reason for this is that it is impossible to select the
system font with height 16 on this platform.  (No idea why, any
ideas?)

Should these tests be written so that a particular font selection is
forced across platforms (e.g. ANSI, 16 point, System), or should the
hardcoded values instead be computed for each particular instance?
