When we are talking about the displace warp documentation i would also suggest
to change the description how it works:

right now it says:

'In type 1, the brightness of the pigment color determines the directions and
amounts points are pushed.'

which is perfectly right, but does not describe things very detailed.  I would
either suggest (derived from what Chris Huff wrote in p.g.):

'It displaces the pattern according to the differences in brightness of the
control pigment's color away from brighter and towards darker areas.'

or in more mathematical terms:

'It displaces the pattern according to the gradient vector of the control
pigment's color.'


I hope suggestion this doesn't sound too picky, but since the displace warp
seems a quite important new feature, I thought it should have a complete
description.
