vtkScalarsToColors::SetAnnotations(...) does not update correctly.

This issue was created automatically from an original Mantis Issue. Further discussion may take place here.

---

If vtkScalarsToColors::SetAnnotations(..,...) is called with certain arrays, and those array are later changed from code outside vtkScalarsToColors, vtkScalarsToColors never realizes the change. Calling SetAnnotations(..) again has no effect.

e.g.

vtkVariantArray* foo=... vtkStringArray* bar=...

/// fill values

stc->SetAnnotations(foo, bar);

/// Render/Update the LUT. Annotations shown/used as expected

/// change values in foo and bar

stc->SetAnnnotations(foo, bar);

/// Render/Update the LUT. Annotations won't be changed, it will still /// use the old values. DOing the following overcomes the issue:

stc->SetAnnnotations(NULL, NULL); stc->SetAnnnotations(foo, bar);
