 replace the blöde gwin by a normal gemwin

yes, very rite

might be right.
rtx, does something like tx-transforming each frame as it arrives
separately (so you get a video that consists of X frames of the size
1*Y) and then interpret this serie of 1 pixel wide frames as the columns
of a new video. (so the second column is delayed 1 frame with respect to
real tx-transform...)
"completely" is surely NO fake and only for legal reasons.

anyhow, there is kind of documentation on http://umlaeute.mur.at/rtx and
maybe in near future there will be really some documentation

maybe it runs even faster under linux ?? i only have win installed
because i have to
and then : w98 does not crash ...

since you are obviously using my compiled Gem it might be my fault.
still haven't found this
