Summary0009073: Translation of line widget fails at certain orientations
DescriptionYou are usually able to click on the line widget and translate it. When doing so, the mouse pointer lines up with crosshairs that are drawn on the line and follow the mouse as it is moved.

If you create a long line and orient it so that one endpoint points near the viewer and one endpoint points away from the viewer then the mouse and crosshairs diverge over portions of the line and it is no longer translatable.

Fixed in VTK CVS.

cvs ci -m "BUG: Computation of parameteric coordinate: t and the closest_point was done in display coordinates. The value t cannot directly be mapped to word coordinates, since it needs to be scaled according to the projection matrix. (The farther you go from the camera position, the larger the increments in t). To avoid this, keep everything in word coordinates by using a picker."
