RFE: List COMP attributes (margin, top fitting, fontpath)

Forgot to post these a year ago and I still miss them every time I used the List COMP

  • margin: similar to how the margin work on COMPs, i.e. textures are only shown inside the margin
  • top fitting: so that we can control how the top attribute is fitted
  • fontpath: so we don’t have to install fonts

Edited: added fontpath
