[Fractdev] Mathtolerance variable

Tim, I've had an extended email exchange with Charles Crocker about a problem he was seeing that relates back to the mathtolerance variable. I see several problems 1) Mathtolerance is not saved in GIF's, 2) Mathtolerance is not saved in PAR's, 3) Mathtolerance is not ever reset to default values. I understand the original intended use of the variable, but with Jim Muth including it on a regular basis with his FOTD it looks like we should incorporate it into the fractal_info and history_info structures. To do this will require increasing the size of the fractal_info structure, which then gets saved to GIF's. Do you recall if this will cause problems with older versions of Fractint reading these GIF's? Jonathan
