[vtk-developers] proposed ENH to vtkImagePlaneWidget

[Dean Inglis]

Oops, no it doesn't: coffee hasn't kicked in yet.  Also,
 ivar 'GrayScaleEnabled' is completely unnecessary.  If
the following lines are added as the default in ::GenerateTexturePlane()

  this->ColorMap->SetOutputFormatToRGBA();
  this->ColorMap->PassAlphaToOutputOn();
  this->Texture->MapColorScalarsThroughLookupTableOn();

and no transparency is set in an external lut then 'normal'
behavior is maintained.  I've checked this in.

Hmmmm, strangely enough, transparency already works without any changes:

try this if you dare ... (in /Examples/GUI/Tcl/ImagePlaneWidget.tcl)
