-.SH RESOURCES
-On some systems (currently, only SGIs), this program can, instead of grabbing
-a desktop image, grab a frame of video from an external camera and manipulate
-that instead.  The following resources control that.
-.PP
-.TP 8
-.B grabVideoProbability \fR(Float)\fP
-What portion of the time to grab video rather than a screen image, 
-between 0.0 and 1.0.  Defaults to 0.5, or half the time.
-.TP 8
-.B videoDevice \fR(Integer)\fP
-The number of the default video input device to check first.  If unspecified, 
-the default camera (from videopanel(1)) will be checked first.  After that, all
-other available video input devices will be checked in order.  
-
-The first one which produces a non-black image will be used.  If all images
-are black, the others will be re-checked a few times before giving up and
-falling back to simply grabbing a desktop image (but note that this takes a
-few seconds, so if you don't actually have any video sources hooked up, you
-should consider turning off video grabbing by setting
-\fBgrabVideoProbability\fP to 0.0.)
-.TP 8
-.B videoGain \fR(Float)\fP
-The amount by which to brighten the grabbed image.  This defaults to 2.2.
