Hello,
Could you review the updated fix:
http://cr.openjdk.java.net/~alexsch/8076545/webrev.02
- round is used instead of ceil
- inverted scales are used
Thanks,
Alexandr.

In this case round may be better. ceil() is more for cases where you
needed "at least X amount of room", but I don't think a font size is
an "at least this much" kind of case.
Also, I've been toying with the idea that use of ceil() and floor() in
any DPI-adjustment equations should really be "ceil(val - epsilon)" or
"floor(ceil + epsilon)" for some small value of epsilon chosen just
large enough to prevent various round-off errors from affecting the
outcome. One idea is for 1/256 as the value of epsilon since that
could equate to the smallest measurable difference in terms of alpha
or interpolation results (or 1/512 for "half the smallest quantum")...

size->cx = (int)ceil(size->cx / scale);
So if size->cx / scale works out to be 12.0001 you will round it up
to 13?
Can you check what pixel size windows gives you in such a case ?
I'd be a little surprised if they did that rather than round.
Is the SetFontProperty that does not accept a scale parameter still used
somewhere ?

- Sergey's point about multi-mon should be checked out.
Windows 8.1 has option "Let me choose one scaling level for
all my
displays".
If I unset it I am able to change the size of all items. However,
the DPI which returns GetDPIForMonitor is still 2 on HiDPI displays.
This version looks fine, but I am sure it can be double checked on
windows 10 at some moment as well.
