[PD] PDP, webcams, and title bars.

First, I have been running PDP on both ubuntu Breezy and Dapper and 
found the Logitech Pro 4000 USB2 webcam having strange video display 
hickups in the stream with both systems. The webcam worked great in 
other apps (vlc, mplayer, etc.) I fixed it in PDP by commenting out code 
in PDP as described in this link:
http://lists.saillard.org/pipermail/pwc/2005-July/000487.html

It seems to me that some aspect of this change should be incorporated in 
the CVS.

Second, I am wondering how to get rid of the title bar for windows 
created in pdp. I managed to nuke it in Linux by using a window manager, 
specifically Devil's Pie:

How might I get rid of the of the title bar when using OS X? IMHO, I 
think eliminating window title bars should be a built-in feature for PDP 
and I am curious why this hasn't been done yet. Is PDP still in active 
development? The code looks mostly from 2003...

Third, on ubuntu Dapper for some reason multiple webcams being displayed 
in multiple windows using PDP is breaking. When I create the first 
window displaying the webcam video, all is OK. When I attempt to open 
the second, unstead of a new window appearing, the first window stops 
updating. I then have to restart Pd to get any reasonable results. This 
is the case using either the pdp_xv or the pdp_glx objects. Multiple 
webcams in multiple instances of VLC is no problem.
