title: Best Icon size for displaying in the tray
body: <p>I am working on a Delphi program which will display an icon on the "tray". I am doing it "the hard way" (using the Shell_NotifyIcon api, etc and not a component, for reasons outside the point here). It's working fine but sometimes it seems like the icon is a little "blurry" in some systems. Now, I have experimented using 16x16 bmp, 32x32, etc. It seems like the system scales it down to the needed size, but the results are different depending on the OS version (or perhaps something else as well)....</p>
  
  <p>Have any of you any experience about the best size and color depth of a BMP to be extracted and displayed on the tray using Shell_NotifyIcon from a ListImage?</p>
