Rafal Pietrak had some questions related to this.[1] So I thought I pick
this topic up again.

They could look like this (some properties may not follow exactly the
syntax rules defined earlier like e.g. form allowing multiple values:

Party:
@text-decoration party {
  form: url(partyhat1.png), url(partyhat2.png);
  amount: random;
  distribution: random area;
  size-variation: 0;
  rotate: 20deg;
  rotation-variation: 10%;
  position: overline;
  order: in-front;
}

Water splash:
@text-decoration splash {
  form: url(splash.png);
  amount: 1;
  distribution: even area;
  position: line-through 50%;
  order: in-front;
}

(BTW: effects like party & water splash are spectacular, but how to control

For 'Party' it's easy as the party hats would be distributed over the
lines. Decorations like 'Water splash' or 'Crossed out' would probably just
be cut off at the end of the line and continue on the next line, i.e. the
decorations only vertically expand over one line, not multiple lines.

The order property handles this.
'in-front': The decoration will be in front of the text, so it may cover
parts of the text.
'behind': The decoration will be behind the text (but in front of a
possible background).

Text shadowing would work the same as it does now. So it styles the text
and also the decoration.
The guys at Medium actually use a background image (a linear gradient) for
underlining, so this is unrelated.
