The current logic to auto-detect HiDPI settings on Linux from #3113 only handles the 2x case. This PR expands it to handle fractional scaling, as described in [this thread](https://lists.apache.org/thread/y5f52bnqx9qvvn35h9lk0mztkv2n35fj). Taking https://github.com/apache/netbeans/issues/7780#issuecomment-2657192464 into consideration, the launcher does not touch the scaling settings if one or both of the `GDK_SCALE` and `J2D_UISCALE` environment variables is set. This PR was tested with both Java 17 and 21 (Eclipse Temurin) on Fedora 42 with fractional scaling enabled in KDE Plasma. Before this PR, no scaling was applied; after this PR, fractional scaling is applied and the following is logged: > Detected 158 DPI in `Xft.dpi` setting; using explicit setting for Java UI scaling (`-J-Dsun.java2d.uiScale=2`) and FlatLaf UI scaling (`-J-Dflatlaf.uiScale=0.822917`) ### PR approval and merge checklist: 1.
