I have played a bit around with gl-floating-const.xml, and there is
quite a few posibilities! For instance, it seems quite easy to create
some fixed-size bubbles with text display only. There could easily be
several different floating HUD's to choose from.

One thing i noticed was that it was imposible to determine how
marble.jpeg will be colorized -- the contrast between dark and light
will vary alot, and it will sometimes be inverted, so that what is
dark in marble.jpeg will end up being light. Perhaps the best bet
would be some kind of abstract, decorative graphic.

Below is a commented version of data/gfx/gl/hud/floating/gl-floating-const.xml
(The only thing I don't understand is gauge-loops and gauge-blink-period,)
