Test that viewer correctly implements the "highlight" object behavior, on a basic HTML-to-CGM link.

At the start of the test, the right-hand frame should display some HTML text containing a string, "Click to select and highlight a WebCGM object." The hyperlink on the HTML text points to a local WebCGM instance, that contains one simple picture with drawings of a pair of cylinder objects, drawn in black on a white background, with APS Id parameters "leftCylinder" and "rightCylinder".

The hyperlink in the source HTML text contains a fragment which selects "rightCylinder" by Id, and specifies the object behavior "highlight" -- upon execution of the hyperlink, the selected object shall be highlighted. The exact method of highlighting is viewer dependent.

The initial view in the left-hand frame is a PNG reference image of one correct rendering of how the target WebCGM instance should appear in the right-hand frame after activating the link in the HTML source instance. There should be no significant visual deviation between the reference image of the left frame and the view in the right frame after link activation, except for the method of object highlighting. The reference image shows one valid method -- the border is outlined in red. Any other visual highlighting method -- e.g., changing the color of the whole object -- is equally acceptable.

You should be able to use the browser "Back" and "Forward" buttons to go back and forth between the target WebCGM picture the source HTML text in the right-hand frame. Note, however, that this latter normal browser behavior is not part of the WebCGM standard, and it is not a pass/fail criterion for WebCGM viewers for this test.
