// comment: This visual program shows some uses of the Overlay module. In two cases, an image is imported, and a new caption is added. For generality, the original image is queried using Inquire to determine its x and y resolution (note that for images imported using Readimage, the first component of the position counts is the number of y pixels, and the second component is the number of x pixels). The resolution and aspect ratio of the original image is used to create a camera for the new caption. 
// comment: 
// comment: If the blend parameter to Overlay is 0.5 (the default), then each image is multiplied by 0.5 and they are added together. This results in a rather dim image. If, however, the blend parameter is set to black, then the original image is used everywhere except where it is black. Where it is black, the caption image is used instead. 
// comment: 
// comment: An example is also shown of setting every black pixel in the original image to red. This is done by chromakeying an entirely red image with the original image using blend=black.  For comparison, the same operation can be performed using Compute.
// comment: 
// comment: Finally an example using a mask for the blend parameter is shown. The mask has a cosine function in the x direction. In this case the blend parameter varies from 1 near the right and left edges (resulting in only the red image) to 0 near the center (resulting in only the original image).
