Specify a gradient of colours to be drawn in the background of the unselected tabs.
For example to draw a gradient that varies from dark blue to blue and then to
white, use the following call to setBackground:
<pre>
cfolder.setBackground(new Color[]{display.getSystemColor(SWT.COLOR_DARK_BLUE),
display.getSystemColor(SWT.COLOR_BLUE),
display.getSystemColor(SWT.COLOR_WHITE),
display.getSystemColor(SWT.COLOR_WHITE)},
new int[] {25, 50, 100});
</pre>
@param colors an array of Color that specifies the colors to appear in the gradient
in order of appearance left to right. The value <code>null</code> clears the
background gradient. The value <code>null</code> can be used inside the array of
Color to specify the background color.
@param percents an array of integers between 0 and 100 specifying the percent of the width
of the widget at which the color should change. The size of the percents array must be one
less than the size of the colors array.

<li>ERROR_WIDGET_DISPOSED when the widget has been disposed</li>
