This is meant as a stopgap for 5.0, with plans to add proper scaled icons in the 6.0 cycle. A function KiScaledBitmap() is added, which works like KiBitmap() except it scales the bitmap according to the calling window's font size. Controls have been added to all the main applications to let the user select scaling manually (these were omitted from smaller apps that didn't already have a place to put them). In addition, in eeschema only, the pixel height of the system font is shown in the options dialog for diagnostics. This is only for collecting feedback before 5.0 release from users with different displays and will be removed.
