[rrd-developers] Rigid sizes for image...

You're not barking, I made this change originally to 1.2.25.  It was 
significant enough to be put off to 1.3, and IIRC I ported the patch to 
the trunk (which was supposedly 1.3) and AFAIK it was working.  I think 
the switch was '--full-size-mode'.  Because of the Cairo switchover, I 
was having some legend spacing issues (independent of my patch) on my 
PPC machine which Tobias couldn't reproduce, but I haven't looked 
further at that - perhaps that unresolved issue is why it's no longer in 
the trunk?
