Bugs with Extrusion Surface Representation

1. A strange graphical artifacts when doing the following :

• Open ParaView
• Tools -> ManagePlugin -> Embossing Representations -> Load
• Open membrane_0778.vtk, Apply
• Switch to Extrusion Surface
• The following is visible until the next render

2. There is some incorrect range calculations when using animations

• Open ParaView
• Tools -> ManagePlugin -> Embossing Representations -> Load
• Open membrane.zip as a file series, Apply
• Switch to extrusion surface
• Play the animation
• the following appears (top is extrusion surface, down is WarpByVector filter)

3. When switching to Extrusion Surface with a 2D view, it could be better to switch to 3D.
