Detailed Description

Display and manipulate a Trapezoid

	 *                        high0   high1
	 *                 |          /---\            |
	 * left border     |         /     \           | right border
	 *                 |--------/       \----------|
	 *            ---------------------------------------
	 *                left    low0     low1      right 
	 * 

Here data intensities between low0 and low1 will appear as bright pixels. Everything else will not appear. Top control the opacity.

As with the histogram, it is possible to visualize only a portion of the ramp, and to zoom and pan it.
