But the font doesn't need to be scaled if JDK supports scale already.
Before the scale support is added to JDK the native scale was supported
for GTK LnF only and using fonts size only. I kept this simplified scale
support for compatibility with Linux OSes for which native scale is not
supported. For Qt based WMs for example.
The question was why the native scale is taken into account, but debug
scale not. In this case we will get a different results if the native
scale=2 was read from J2D_UISCALE/scale-factor/GDK_SCALE/Xft.dpi or was
set for debugging by the user.
I think the logic should be:
- Take debug scale into account if it was set and skip all others.
- Check J2D_UISCALE
- Check scale-factor, text-scale-factor, text-scaling-factor.
- Check Xft.dpi.
- If non of them was set then scale=1 should be used.
I guess text-scale-factor, text-scaling-factor are text related scales,
but we use it as a generic one, so why Xft.dpi should be different?
