Well, actually you can set the value to zero but the particles displayed doesn't update correctly. There are also some
seemingly related glitches concerning the Amount parameter. See attached video.

the problem is that the reallocation of the particle buffer did not 
occur with zero particles

please only use patch23003-2.txt the other file is incorrect.
