[GRASS-dev] TclTk animator finished - replaces xganim

[Michael Barton]

I finished updating the new TclTk animation module and committed it to the
cvs. It does pretty much what xganim did, but with somewhat nicer interface.
It also has several important improvements over xganim.

Enter up to 4 animation series "views", following same format used by xganim

    rast[1-n],rast2[1-n],...

where rast[1-n] refers to raster maps rast1,rast2,rast3,...,rastn

You can also enter maps in the format, not supported by xganim

    rast1,rast2,rast3,...,rastn

An important improvement is that xganim currently will only actually work
with a series of 10 maps, rast[0-9]. Because it seek only individual
characters at the end of each map in the series, it cannot recognize numbers
higher than the numerals 0-9. That is 11 is simply two ones. The TclTk
animator WILL recognize these as numbers, so that you can animate a series
of maps limited only by system capabilities.

As with xganim, single animation series will be displayed to fill the TclTk
canvas window; a multi-view animation (up to 4 views) will divide the canvas
into 4 subwindows with an animation series in each subwindow. Up to 4
simultaneous animations can be run.

Another improvement over xganim is that you can animate series with
different numbers of frames simutaneously (e.g., a multi-view animation with
a 100 frame animation in one subwindow and a 20 frame animation in another
subwindow).

I'm not sure if the labels are working properly yet, but everything else
seems to be. Give it a try and let me know if you run into any snags.
