[Paraview] text glyph

[David E DeMarle]

I'm thinking we should put text labeling in as an auxiliary
representation (like cube axis). It will borrow from the info/geo vis
representations that downsample and place a readable number of labels.
(Side note: Visual clutter is more of a problem than speed. You can
only draw a few hundred words on any given display and have them be
legible. Thus visualization was invented.) The representation will
have a checkbox (with a popup warning) that the user can hit to tell
it not to downsample.

In any case, someone will have to spend a week or four implementing
that, managing the streaming and/or server side rendering such that
the client does not get overwhelmed and crash. If you want to see this
in ParaView soon, please vote for it on user voice to give it some
priority, or better yet implement and submit a patch.
