Each frame would be displayed for 1 second before the next one is displayed. The cycle repeats after the last frame in sequence shown.</p>

 <p>This keyword causes the texture coordinates to rotate. The value is expressed in degrees rotated each second. A positive value means clockwise rotation. A negative value means counterclockwise rotation. For example "tcMod rotate 5" would rotate texture coordinates 5 degrees each second in a clockwise direction. The texture rotates around the center point of the texture map, so you are rotating a texture with a single repetition, be careful to center it on the brush (unless off-center rotation is desired).</p>
 
 <h3>tcMod scale <em>sScale tScale</em></h3>
-<p>Resizes (enlarges or shrinks) the texture coordinates by multiplying them against the given factors of sScale and tScale. The values "s" and "t"conform to the "x" and "y" values (respectively) as they are found in the original texture TGA. The values for sScale and tScale are NOT normalized. This means that a value greater than 1.0 will increase the size of the texture. A positive value less than one will reduce the texture to a fraction of its size and cause it to repeat within the same area as the original texture (Note: see clampTexCoords for ways to control this).</p>

 <h3>tcMod scroll <em>sSpeed tSpeed</em></h3>
 <p>Scrolls the texture coordinates with the given speeds. The values "s" and "t" conform to the "x" and "y" values (respectively) as they are found in the original texture TGA. The scroll speed is measured in "textures" per second. A "texture" is the dimension of the texture being modified and includes any previous shader modifications to the original TGA). A negative s value would scroll the texture to the left. A negative t value would scroll the texture down.</p>
