QC4

I'm not going to go into the excruciating detail that I do on my blog, but while writing a bug report on QC4 today I noted a fun, if not so important, "tidbit":

If one creates "Mesh Filters" and "RSS Visualizers" folders for Developer/Library/Quartz Composer/Examples, what are now "dead links" on the Template page will now trigger the newly created folders to open in Finder, just like is typical with the links for the other Template types.

When looking at a recent post by yanomano about array size, I realized that the Snow.qtz example from the Apple Developer Examples "OpenCL" download suffered from a very similar code setup to set the particle positions.

I have changed that so that when the particle count is reduced, that the structure reduces correctly.

Also, I have noted that when the qtz is initialized, that it runs a bit "oddly" until particle count is reset. This amounts to the distribution of particles not being as even looking, and performance being a bit more uneven. I'm not sure if this has always been the case with this composition, but I've added a small portion to the setup to create a pulse at startup that quickly adds and subtracts a particle on startup, and any time that particle count is changed thereafter. This smooths performance on my system.
