[Paraview] Python state trace w/glyphs not working

[pat marion]

Pushed the fixes to git.

Here is python macro I've been using to test the trace state.  I add this to
the macro toolbar so I can run it with one click.  It does a trace state,
clears all the sources & views, then executes the trace to restore your
state.  This means you can click the button at any time and you *should* get
back what you started with.  Of course, there are some pipelines that do not
restore correctly (just recently noticed the 2D Render View is not available
in python...)  Any errors that may be produced will be displayed in the
python console, but probably not echoed to stdout.

# reload_state.py
from paraview import smstate

def clear_proxies():
   groups = ["sources", "representations", "views",
                   "implicit_functions", "piecewise_functions",
                   "lookup_tables", "scalar_bars", "selection_sources"]
   for g in groups:
       for p in servermanager.ProxyManager().GetProxiesInGroup(g).values():
           Delete(p)

def reload_state():
    smstate.run()
    trace_string = smstate.smtrace.get_trace_string()
    clear_proxies()
    code = compile(trace_string, "paraview_trace", "exec")
    exec(code)

reload_state()
