Description

When you scroll within a slider of a 3 or more dimensional image DatasetView::setPosition() gets called more than once. First the current value is sent, then the new value, then the new value again. Because of this projector.map() is getting called multiple times.

Do one of two things:
1) determine why its getting called multiple times and avoid it
OR
2) cache last dimensionalIndex and value passed in and only call the drawing code when the position or dimensionalIndex changes
