Apart from the obvious (and generally desired) effect of displacing an image, the displace node also causes the output to get blurred unnecessarily.
See the comparison below:
no displace - http://www.pasteall.org/pic/show.php?id=3555
with displace - http://www.pasteall.org/pic/show.php?id=3556
It would be awesome if the image stayed (more or less, without aliasing) crisp. Since our current project (http://www.artificial3d.com/omega/) relies heavily on heat effects, it would be a pity if all the details get lost in the process :)
thanks a bunch!

I'm not familiar with the nodes code too much, but a note on what looks suspicious.
in CMP_displace.c, lines 119-120:
/* scaled down to prevent blurriness */
/* 8: magic number, provides a good level of sharpness without getting too aliased */
dx /= 8;
dy /= 8;
Perhaps increasing this value (to get smaller sampling step values) would help, since blur implies that too many pixels are getting sampled by this value being too large?

i hope this makes it more clear :)
