[IDV #TZB-248628]: Time Driver bug? in time-height section display.

I'm just glad it was user error and not my code. ;-)

The animation time sets (drivers) are not shared between the different views, 
but other properties are (like the current time set). I'm scared to share the 
animation set by default - I don't know what the result would be.  I vaguely 
remember we used to share them and badness ensued. :-(

You can control the properties that do get shared with the Animation Properties 
Dialog (click the "i" button on the widget).  You'll see that you can share 
absolute times (the default), or relative times (useful for syncing disparate 
time sets like a 12month climate dataset and a 12 month observed), or none for 
no sharing.  You can set the animation group so that if you had 4 views, you 
could have 2 animating together and another 2 animating together by setting 
them to different share groups.  By default, all view windows are in the same 
animation share group and sharing by absolute times.  I used to go over this in 
the satellite/radar section of the User Workshop:

http://www.unidata.ucar.edu/software/idv/docs/workshop/datadisplays/imagery/Level3RadarImage.html

You can create a multiple panel display through the File->New->View Window->Map 
View menu. For the multiple display, the projections are shared by default as 
well.  But you can set up separate windows to share projections through the 
Projections->Set Share Group and Share Views menus.  At one time I thought of 
setting a global time driver which is useful for multipanel displays, but the 
biggest problem there is how to let the user specify that.  I guess if they 
could share the animation time set, that would do the same thing.
