All interfaces, menus and dialogs associated with the new EDEN editor don't seem to scale according to the aforementioned setting. This is an issue when using high resolutions especially, as the EDEN editor can be extremely hard to read and navigate while the rest of game's interfaces scale accordingly.
I did notice in one of the EDEN functions (fn_initPixelUI) a command called "pixelScale" is mentioned along with pixelW and pixelH, but it doesn't seem to have been implemented unlike pixelW and pixelH.
