I think the answer here is "3-D plots". When I make a 3-D plot I want the text
to stay "on the glass", not rotate with the plot (and the data coordinate
system). In some cases you might want the text to rotate with the plot (a la
PLOT_3DBOX), but the downside is that the title can be impossible to read from
some viewing angles.

I'm not sure what you mean by jumping around. If I zoom the view like this,

itool_id = itGetCurrent(TOOL = itool_obj)
view_1_id = itool_obj -> FindIdentifiers('*VIEW_1')
rc = itool_obj -> DoSetProperty(view_1_id, 'CURRENT_ZOOM', 1.25)
itool_obj -> RefreshCurrentWindow

the text zooms also. I find this disconcerting, as it changes the "normalized"
coordinates, but this is the only way I can find to do this, as VIEW_1 has a
"Zoom factor" property, while the visualization layer (apparently) does not.

I suppose a possible solution is to add a second view with only an annotation
layer. That view could be left alone when the view containing the data is
zoomed.

By the way, wouldn't it be nice if you could use the Visualization Browser or
the Property Editor to get the ID's for all of the objects and properties? The
Visualization Browser says the property is "Zoom factor", while the actual ID is
"CURRENT_ZOOM". The only way I know to find these things is by fooling around
with FindIdentifiers

viz_ids = itool_obj -> FindIdentifiers('*Visualization Layer*')
PRINT, viz_ids
