eirikbakke opened a new pull request, #8309:

   Here are a few more changes to ensure that [SVG 
icons](https://github.com/apache/netbeans/pull/8083) render at full resolution 
on HiDPI screens.
   
   This PR handles the transformation from
   `Graphics.drawImage(ImageIcon, x, y, null)`
   to
   `Icon.paintIcon(null, Graphics, x, y)`
   at various places in the codebase.
   
   This fixes e.g. poor-resolution lightbulb icons in the editor gutter on 
Windows at fractional HiDPI scale factors.
   
   All simple such cases were found by grepping for "drawImage" and reviewing 
each case. Test classes and NBI related classes were skipped.
   
   This is mostly an improvement for screens with a fractional HiDPI scaling 
(e.g. 150%) on Windows. On 200% scaling (including on MacOS), icons are drawn 
properly even with drawImage, due to ImageUtilities returning 
MultiResolutionImage instances nowadays with 1x and 2x resolutions present. The 
latter is still a good fallback for cases that may not yet be covered otherwise.
