Test viewer capility to recognize and effect picture behavior request on a basic CGM-to-CGM link, for picture behavior "_blank".

At the start of the test, the right-hand frame should display a WebCGM instance containing a simple picture with three objects: a magenta rectangle, a cyan circle, and a red triangle, all with thick black borders. The red triangle object (APS) contains a hyperlink to another local, one-picture WebCGM instance, that contains a drawing of a pair of cylinders. The hyperlink is a 'linkuri' APS attribute, and the picture behavior "_blank" is contained on a "#" fragment on the URI parameter. No object selection or object behavior parameters are associated with the 'linkuri'.

A mouse click anywhere over the red triangle (labelled "third object") should cause the hyperlink to be executed. This should result in a new window being opened and the entire target WebCGM picture to be displayed in the new window. Details of the size of the new window, and of the target WebCGM picture, are unspecified in WebCGM 1.0.

The initial view in the left-hand frame is a PNG reference image of the target WebCGM picture that should appear in the new window, that is opened upon execution of the link.
