/**
 * Simple test program that demonstrates a fatal infinite loop in
 * Rectangle2D.intersectsLine
 * The implementation of intersectsLine uses a while loop that makes an
 * incorrect assumption that arithmetic rounds nicely. However,
 * it doesn't, and there is a while loop that never exits.
 *
 * This may seem unusal - but in fact it *regulary* hangs up our drawing program
 * that lets users zoom out, and thus effectively specify points at very high
 * precision.
