Message:

• Add contour3d (isosurface geometry) command to vtkvis
• Use depth peeling algorithm (order independent transparency) by default, add 'renderer depthpeel' command to toggle.
• Use tri strips in some geometry generators for better performance
• Heightmap: 2D slice resampling of non-image 3D datasets (e.g. points, ugrids) Set a default scaling based on data range. Still some problems where images from resampling have zero values in out-of-bounds pixels (probe filter creates a mask array that could be used). Still need a method/heuristic to select image resolution when resampling.
