[Win32] Wrong font size is selected when opening FontDialog (monitor-specific scaling)

[wahlbrink]

When opening a FontDialog with an initial FontData set on a monitor with scaling factor != 1, the size initially selected in the dialog is the font size multiplied by the scaling factor.

For example: when opening the FontDialog on a monitor with zoom 200% and an initial font with size 10, the font size selected in the dialog is 20.

To Reproduce

• Open the font dialog from the "Colors and Fonts" preference page of the Eclipse IDE .

Environment:

1. Select the platform(s) on which the behavior is seen:

• • All OS
• • Windows
• • Linux
• • macOS

2. Additional OS info (e.g. OS version, Linux Desktop, etc)
   Windows 11

3. JRE/JDK version
   JDK 21 (Adoptium)

Version since
tested with: Eclipse 4.38 Build id: I20251201-0920

but the bug was already present in the previous version.
