[x3d-public] announce: update releases for X3D Schematron and the X3DJSAIL Java library

[Don Brutzman]

Thanks for the trouble report.  Please include .x3d file in such reports so
that repeatability is possible.

   - Ticket #42 Missing OrthoViewpoint.fieldOfView when using MFFloat
   - https://sourceforge.net/p/x3d/tickets/42/

Of relevant note is presence of following HelloWorldProgram.java "smoke
test" program, which demonstrates successful operation.  I just adjusted it
to include the OrthoViewpoint  tests in all of the various output files.
Still having some trouble getting fieldOfView output (not sure why) and a
properly valid pattern for Layout publication.

   - HelloWorldProgram.java

my updated excerpt:

>         layout.setAlign("LEFT");
>         layout.setAlign(Layout.ALIGN_LEFT_BOTTOM);
>         layout.setAlign(new java.lang.String[] {"LEFT","BOTTOM"});
> //      layout.setAlign(Layout.ALIGN_LEFT); // TODO test singleton
> enumerations
>         System.out.println("layout.getAlign=" + layout.getAlignString());
>         System.out.println("layout field smoke tests = " +
>                    Boolean.toString((new
> MFString(layout.getAlign())).toString().equals((new
> MFString(Layout.ALIGN_LEFT_BOTTOM)).toString())) +
>                    " (through manual debug checks)");
>         LayoutGroup layoutGroup = new LayoutGroup("SpecialTestLayoutGroup")
>                    .setLayout(layout);

>    // valid, special-case utility method

>     // valid, special-case utility method
>         orthoViewpoint.setFieldOfView(new float[] {1, 2, 3, 4});
>    // valid
>         orthoViewpoint.setFieldOfView(new MFFloat(new float[] {1, 2, 3,

As the head of the prior log file shows, the Ant tests are in the parent
stylesheets directory, target *test.X3DJSAIL* and *test.X3DJSAIL.Schematron*

Posted another X3DJSAIL update.  Good luck on next steps.

all the best, Don
