[Paraview] Displaying FPS as annotation

[Adam M. Smith]

Hello All,

I want to show the framerate of my visualization as part of the corner
annotion.  I see that I can use tcl expressions in these boxes but I'm not
sure how to proceed.  I tried calling ListMethods on the RenderModuleProxy
but it doesn't seem to have any fps-realated methods.  Is there some
simple thing I can do other than... maybe register a certain piece of
timer setup at the start of an animation using the command system, and
place expressions in the corner annotation to read the timer status?  This
feels like a very simple problem

Thanks for the help!
