Fix drawing artifacts with dives that have samples past the dive duration

Browse source 
The UEMIS Zurich SDA keeps recording samples for quite a while after the
dive ended.  These provide no additional information, but confuse our
drawing algorithm as they can cause us to draw both the depth and tank
pressure plots beyond the right edge of our canvas.

Stop drawing if sample->time.seconds is larger than dive->duration.seconds.
