Wine fonts too big for their input fields.

The fields in my case are 4 numbers.

What the "right" font should be is a bit of a mystery to me. From traces 
with the font and edit debug channels turned on, it appears to me the 
application was selecting "MS Shell Dlg". So in my test app, I 
duplicated the selected font:

afont = CreateFont(-11, 0, 0, 0, 400, 0, 0, 0, DEFAULT_CHARSET, 
"MS Shell Dlg");

And indeed on Win2k, that produces an identical result to the Xilinx 
app. On Wine, the font appears to be similar but not identical. As far 
as the characters go, I can see that the '1' has an extra pixel to the 
right at the bottom. Most of the other characters appear to be pixel 
identical (though the '7' is rendered one pixel to the right of where it 
is on Win2k). The biggest difference though, is that the numbers are 
aliased on Wine, and not on Win2k. I'll see if I can figure out what 
fonts are actually being used; I don't really know offhand how to go 
about doing that.
