[Tioga-users] Setting absolute size of figure

[Bill Paxton]

Hi,

This email is a comment on the issue of unintentionally getting  
multiple copies of additions to the tex_preview_preamble string.  I  
now think this is simply a bug in Tioga.  We get extra copies  
appended because the string is not being reset when a file is  
reloaded.  We do automatically call reset_figures to clear the list  
of figures (or else we'd be having the same problem with the list of  
figures as well!) -- so my intention is to add to reset_figures so  
that it resets the entire figuremaker state to defaults.  That fixes  
the preview_preamble problem and also eliminates one possible source  
of nasty confusion in which a Tioga figure gives different results  
depending on how many times the file has been reloaded!

Unless I hear violent objections, that's what I'll do for the next  
release.

Cheers,
Bill
