Message:

Handle 2D datasets with offset from origin or in principal planes other than XY.
Add return value for many methods, e.g. creating graphics objects
Add query for server's current list of datasets
Add pixel/world coordinate query of vector fields
Add pixel coordinate support for setting image camera zoom region
Add Heightmap wireframe, surface visibility toggles
Add Point size setting for polydata
Use custom version of 2D axes, fixes tick/label direction in XZ view
Put contour isolines through stripper to remove gaps in line rasterization
