<strong>composite</strong> composites (combines) images to create new images.
<p><em>base-image</em> is the base image and <em>change-image</em> contains the changes.
<em>ouput-image</em> is the result, and normally has the same dimensions
as <em>base-image</em>.
<br>&nbsp;<br>
<p>
The optional <em>mask-image</em> can be used to provide opacity information
for <em>change-image</em> when it has none or if you want a different mask.
A mask image is typically grayscale and the same size as
<strong>base-image</strong>. If <em>mask-image</em> is not grayscale, it is converted
to grayscale and the resulting intensities are used as opacity
information.
