Stereo Anaglyph Images: Generate a stereo image from two source images

This class can be used to generate a stereo anaglyph image from two other source images.

It can process two source images that define the left and right views of a picture and compose a stereo image that can be viewed with special glasses to appear to be 3D.

The class can read source images in any format supported by the GD library. The resulting picture is returned as a GD image resource handle.
