.SH DESCRIPTION
The \fIslidescreen\fP program takes an image, divides it into
a grid, deletes a random square of that grid, and then randomly slides
The size of the grid cells. Default 70 pixels.
.TP 8
.B \-ibw \fIpixels\fP
-The size of the "gutter" between grid cells. Default 1 pixel.
+The size of the "gutter" between grid cells. Default 4 pixel.
.TP 8
.B \-increment \fIpixels\fP
How many pixels by which a piece should be moved when sliding to a new
the motion of each segment. Default 50000, which is 0.05 seconds. This
is closely related to the \fI\-increment\fP parameter.
.TP 8
-.B \-delay \fImicroseconds\fP
+.B \-delay2 \fImicroseconds\fP
How much of a delay should be introduced between the end of the motion of
one segment and the beginning of the motion of another. Default 1000000,
which is one second.
