the water is represented by a filled box within a outlined box.
the blocks are formally 100 high and then brought back to 67 by a transformation matrix.
the transformation matrix also reverses the y-axis, so that altering `height` has effect on the *top* of the coloured area.

`height` is in an attribute, so altering it looks simpler than what we already do for the style.
