[Polyworld-develop] short updates

[Larry Y. <lsy...@be...>]

As some discovered, I failed to 'cvs add' the 
utils/objectxsortedlist.* files initially.  Those are in.

I also failed to 'cvs add' environment/brick.* files.  Those are now in.

I did a 'cvs remove' on Polyworld.xcode and its contents and 
committed it, as this is strictly for the old version of Xcode, which 
we no longer support.  Next time you do a 'cvs update', make it a 
'cvs update -dAP' to be sure everything is fully up to date and the 
old .xcode project gets purged from your system.

I successfully built and ran Polyworld on my Intel iMac.  Better 
testing is needed, but speed seems comparable on this 2GHz dual core 
Intel box to my dual 2.5 GHz G5 box.  Amazing.  I don't know if 
byte-ordering issues in the genetic bit-twiddling will surface or not 
yet, and whether identical runs on PPC and Intel produce identical 
results is yet to be determined.

PwMoviePlayer has a problem on Intels, due undoubtedly to the byte 
ordering.  It runs and plays the movie, but the entire screen is 
saturated with red, probably due to a 0xff being shoved into the byte 
that was intended for the alpha channel.  Off hand, G looks G, and B 
looks B, but R is messed up, as is, presumably, alpha.
