      Issue error if vtkAlgorithm::GetInputConnection called on wrong port · 248bf676
      Sankhesh Jhaveri authored
      The original logic was issuing a warning if querying a connection that
      was outside the range of input connections to the port. This led to
      warnings in application code that was querying if a particular algorithm
      had input connections yet.
      
      The new logic issues an error if the port in reference, is outside the
      normal range of input ports for the algorithm but silently returns a
      nullptr when the connection index is outside the range of connection
      indices for the port i.e. no more warning when no input is provided.

      Backport 'reslicemapper-border' to release branch. · 508c2ada
      David Gobbi authored
      When MultiSamples are used in VTK (which is the default on Windows
      and Linux), a thin border appeared at the edge of the image if the
      the image pixel values were not zero at the edge.  The thin border
      is the result of the zero 'Background' value of vtkImageReslice.
      All of the "Background" pixels produced by vtkImageReslice are
      supposed to map to beyond edges of the polygon used to render the
      image texture.  However, MultiSamples causes the edge to be soft,
      and the coloring of these background pixels bleeds into the edge
      of the polygon.
      
      The solution is to tell vtkImageReslice to add a bit more edge
      tolerance when clamping its interpolation coordinates.  This moves
      the 'Background' beyond the edge of the polygon, so that these
      background pixels no longer bleed into view.
