.SH DESCRIPTION
Loads a random sequence of images and smoothly scans and zooms around
in each, fading from pan to pan.
.B \-root
Draw on the root window.
.TP 8
-.B \-duration \fIseconds\fP
-How long to display each image before loading a new one.
-Default 30 seconds.
+.B \-pan \fIseconds\fP
+How long each pan should last. Default 6 seconds.
+.TP 8
+.B \-fade \fIseconds\fP
+How long each fade (in and out) should last. Default 2 seconds.
+If set to 0, then no cross-fading will be done (all transitions
+will be jump-cuts.)
+
+Note that fades are included in the pan, so \fI\-pan\fP should
+always be longer than \fI\-fade\fP (it is auto-corrected if not.)
+.TP 8
+.B \-zoom \fInumber\fP
+Amount to zoom and pan as a percentage. Default: 75, meaning that
+75% or more of each image will always be visible. If set to 100%,
+then the images will always fill the screen, and no panning or
+zooming will occur. Images will still smoothly fade from one
+to another, however, assuming \fI\-fade\fP is non-zero.
.TP 8
.B \-delay \fInumber\fP
Per-frame delay, in microseconds. Default: 20000 (0.02 seconds.).
.TP 8
-.B \-fade | \-no-fade
-Whether to fade between pans.
+.B \-cutoff \fInumber\fP
+If the frame rate drops below this number of frames per second, then
+certain features will be turned off automatically (first zooming,
+then, if the low frame rates persist, fading.) Default 5.
+
+The idea here is that if your machine can't maintain a decent frame
+rate, then it must not have fast 3D hardware, so we might as well
+behave in a simpler manner. Set this to 0 to disable this check.
.TP 8
-.B \-zoom \fInumber\fP
-Amount to zoom and pan as a percentage. Default: 75, meaning that
-75% or more of each image will always be visible.
+.B \-titles
+Whether to print the file name of the current image in the upper left corner.
.TP 8
-.B \-fps | \-no-fps
+.B \-fps
Whether to show a frames-per-second display at the bottom of the screen.
+.TP 8
+.B \-debug
+Prints debugging info to stderr.
+.TP 8
+.B \-wireframe
+Instead of loading images, simply animates representative grids instead.
