TODO list for next Rappture and Render Servers release.

• (ldelgass) Merge in nanovis2 branch after merging 1.2 with trunk.
• (ldelgass) Update VTK pre 6.0 to current head
• (gah) Fix X,Y,Z button placement on isosurface cutplane settings tab page
• (gah) Make isosurface translucent in default state
• (gah) Isosurface widget: Fix isoline color dropdown initial state to match line color, also fix 'none' option
• (gah) Make streamlines cutplane initial state match isosurface (X/Y/Z buttons on, but cutplanes off).
• (gah) Fix documentation for <field>, <mesh>, <cloud>, and <unirect2d> to reflect changes.
• (gah) Add curvilinear type to <mesh> documentation.
• (gah) Implement and write test for <unstructuredgrid> element in <mesh>.
• (gah) Fix <field> and <mesh> examples to include new types.
• (gah) Merge Rappture1.2 with trunk.
• (gah) Bug: Multi-field problems: limits, settings colormaps.
• (ldelgass) Write stats for vtkvis.
• (gah) Bug: vtk data 2D field coming up as heightmap in contour4.
• (gah) Added contour4 example of mulitple fields in a single vtk file. This is broken in the <field> object in how it collects limits for each field. It's broken in the client viewers in how they ask for field limits.
• (gah) visviewer class fix add viserror command to read error message (after being told the number of bytes that follow). This will be reported as a dialog box specific to a render server error (usually a problem with the data).
• (gah) Add ridiculous number of tries before generating a bgerror.
