Grayscale lookup table produces overly quantized display
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Loading a floating point scalar field and displaying using the grayscale lookup table (with 256 entries in lut) produces a quantized image. Other colormaps produce a smoothly varying field but the grayscale lut overly quantizes the table (looks as though only 20 grayscales are used).
Loading the same data in Paraview 1.4 does not exhibit this problem
