From: Nirav Patel
Subject: Patch from Martijn Schmidt. Remove V4L support.
 With modifications by Nirav Patel.  V4L has effectively
 been deprecated from the Linux kernel as of 2.6.38. Support
 in pygame was just a placeholder, and removing it
 will not change any functionality.
Origin: Upstream, http://svn.seul.org/viewcvs/viewvc.cgi?view=rev&root=PyGame&revision=3077
Bug-Ubuntu: http://bugs.launchpad.net/bugs/755980
Last-Update: 2011-06-20

Upstream-Commit-Date: 2011-04-23 14:39:19 -0400
Comments-Ubuntu: 
 Minor changes made by Scott Moser to apply upstream patch to 1.9.1release
 This patch can be dropped when 1.9.2 is released and integrated.
