New pipeline browser icons
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
We need better descriptive icons in the pipeline browser. The icons should give visual cues as to what type of view can be used with the particular filter. Thus get rid of the teardrop (source) and filter icons.
Right now there are two types of views. There is a 3D geometry view. The corresponding icon should be a simple 3D structure (rotated, shaded cylinder?). There is also a plot view. The corresponding icon should be a little plot.
