Description
Constructing a WritableImage with a width or height <= 0 with throw an exception in the toolkit:

java.lang.IllegalArgumentException: Image dimensions must be > 0

        at com.sun.prism.Image.<init>(Image.java:118)

        at javafx.scene.image.Image.<init>(Image.java:662)
        at javafx.scene.image.WritableImage.<init>(WritableImage.java:70)

This should be documented if this is the desired behavior (which I think it is).

Fixed with changeset: changeset: 1180:7eb62ef86e4f date: Tue Jun 05 18:58:25 2012 -0700 summary: Fix RT-21831: Specify ranges for WritableImage constructor parameters. This is a doc-only fix so there are no unit tests for this particular fix. The Image Ops unit tests, though, should cover invalid arguments (see RT-21866).
