hi thorolf,
now, no matter what i do, the positions of the moving objects and their representations in the snapshots are always slightly off.
i know the problem and it was also mentioned/discussed in an exchange on the gem-dev list in august or september, search under motion blur. fact is that the trails and motionblur only work "exact" when the gemwin is rectangular and the snap and the square where the texture is glued onto has the same size then the gemwin. why - i dont know - and was also back then not answerd.

as a result, the trails are not
what they are supposed to be - they tend to vanish in the middle of the snapshot, instead of representing the motion of the moving objects. everything is perfectly fine when doing the same thing with just a single [rectangle 5.33333 4] filling the whole screen, so it works in principle. but i do need to have other parts of the scene visible as well ...
i guess that OpenGL's perspective calculations are kicking in here - is there any way of preventing this? i extensively played around to get this straight: among other things, i tried [ortho], another attempt was to make the single rectangle partly transparent with [alpha], but none of these ideas worked.
i greatly appreciate any help -
thank you, thoralf.
