- fixed very slow page refresh (related to part center query from cosmetic 3D vertex)
- fixed bug when annotating a view that has an invalid part reference
- using scale 1.0 for arrow ends (instead of 4.0)
- improved naming of balloons (part name appears more clearly, balloon numbering is at the end)
- balloons for parts that were already in the previous step are hidden by default
- disabled highlighting of part drawing related to the selected balloon (for performance reasons)
- added possibility to explicitely set the display name of a part (instead of using the file name)
- added workaround for balloons that are not rendered until selected
