[Therion] drawing files with unnecessary large extents created by therion/topparser

[Martin Sluka]

Last line of xvi file:

set XVIgrid {-1597.48031496 -19633.6220472 78.7401574803 0.0 0.0 78.7401574803 492.0 268.0}

First two number are too big.

The same in th2 file - first 4 lines:

encoding  utf-8
##XTHERION## xth_me_area_adjust -7709.75 -4195.57 46258.49 25173.45
##XTHERION## xth_me_area_zoom_to 50
##XTHERION## xth_me_image_insert {6335.80417323 1 1.0} {21161.1492913 408.13} ptopoQuackery/408-SurfaceTension_p.xvi 0 {}

The second line shows too big size of area and 4th line too big coordinates. 

BTW, zoom factor 50 is too low for such xvi file - line 3. try to change it to 400 for beginning.

You may edit all this parameters in th2 file manually in xtherion map editor.

> this is typical for PocketTopo and lines created by mistake, if one didn't switched pen to moving mode before transport of PDA and PocketTopo created a "missed" line somewhere in border of drawing area. It could be just one very short and practically invisible line. Try open the xvi file by plain text editor and find such a lose line.

> There is something about the drawing extents that is not right.  Not sure if it is just a gap in my Xtherion knowledge, or if there is something unusual about how TopParser (and sometimes the therion convert) creates the files.
> Can I fix it by manually changing something after the file is created?
> Most times this does not happen with Therions converter.
