/**
 *  Defines a line chart of 5*sin(x) & 5*cos(x) vs x that extends beyond
 *  both the plot area and the decorated chart along all four edges, so
 *  that we can test the new w 2.5 setClipToPlotArea and
 *  setClipToDecoratedChart methods with both canvas and HTML elements.
 *  <p>
 *
 *  This test requires reviewing the HTML elements in Firebug to verify
 *  that only the actually visible image elements (representing square
 *  point markers) are present in the DOM, and that the canvas rectangle
 *  is collapsed down to the clipped-to region. Note that without such
 *  Firebug checks, the "visibility: hidden" on the various parent
 *  panels could be simply hiding these elements (or excess canvas
 *  pixels) which would result in wasted time/space.
