Test basic correct viewer handling of 'para' APS and associated attributes, as link target from other WebCGM content.

This is a companion test to otherAPS-para-BE-01 -- the same content files are used, but their roles are reversed. 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. These are labelled respectively "first object", "second object", and "third object".

The magenta rectangle ("first object") contains a hyperlink to another local, one-picture WebCGM instance, containing two para objects (this is the root file of otherAPS-para-BE-01). The 'linkuri' identifies the blue 'para' by id, and contains no object behavior parameters. The red triangle ("third object") contains a hyperlink to the same local, one-picture WebCGM instance, and identifies the green 'para' by id. This 'linkuri' contains the object behavior parameter, "view_context".

Clicking anywhere over the magenta rectangle ("first object") should cause the target WebCGM instance to be displayed in the right-hand frame, in a full picture view with the blue 'para' object highlighted. The primitives themselves should be highlighted.

Clicking anywhere over the red triangle ("third object") should cause the target WebCGM instance to be displayed in the right-hand frame, in a zoomed view with the green 'para' object highlighted. The dotted rectangle labelled "viewcontext" should fill the display frame, and the dashed rectangle labelled "region" should be highlighted.

The initial view in the left-hand frame is a PNG reference image of the target PNG image which should appear in the right-hand frame upon activating the "first object" (magenta rectangle) link in the WebCGM 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 -- each of the text strings comprising the para object is outlined in red. Any other visual highlighting method -- e.g., changing the color of the whole object -- would be equally acceptable.

The portion of the PNG reference image within the dotted "viewcontext" rectangle should fill the display frame for the hyperlink aimed at the green para. The highlighting of the blue 'para' would be off, and there would be highlighting corresponding to the dashed "region" rectangle.

You may 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. 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. If it doesn't work, use "Reload" or "Refresh" between link executions, or go the table of contents and back. Also note that this pair of tests (this one and its BE-01 companion) are cross linked.
