In short, this issue caused by average font width difference due to internal
fixed-point fractional errors.

It occurs following steps:
1. Calculate ppem (pixel per em). On both of systems, VL Gothic 24 pixel cell
height corresponds to 19 ppem.
2. Calculate the average font width. Wine says it's 10 pixel. But, Windows says
it's 9 pixel.
3. As VL Gothic is fixed-pitch font, full-width character advance is twice of
average font width. So, Wine uses 20 pixel advance, Windows uses 18 pixel
advance.
4. Finally, for 400 pixel message box, 22 Japanese characters are displayed in
Windows, but 20 characters are shown in Wine.

My proposed patch adjusts the font average width in step 2.
