Prism: View controls are buggy
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
The view controls for prism seem to work initially, but after some number of manipulations they stop having an effect and eventually they end up hanging or crashing the session.
Also, the user selects two variables for x and y axes and a third for a warped surface; the ranges of the x and y axes can be controlled by threshold sliders. The view controls offer the user to rescale to the full bounds, the threshold bounds, or to arbitrary values the user inputs. If the user has moved the threshold sliders, the "threshold bounds" for the warped surface variable should be updated as well - the current behavior is that the full bounds are shown for the z variable.
