The Blender icon must not be used to refer to anything that is not Blender itself. Using the Blender icon on its own to refer to .blend files or the currently open file is a no-go, which was brought up by Ton. This does the following changes to the icon file: * Add new "Current File" icon * Change the .blend file icon to contain a file icon with the Blender logo, but not merely the Blender logo. * Change the backup .blend file icon accordingly. The new "Current File" icon is used in the Asset Browser, but could/should be used in the Outliner as well. That needs more design discussion though.
