Re: [Plplot-devel] precision problems in c_plmtex()

[Alan W. I. <ir...@be...>]

I am very happy you have moved to normalized device coordinates for
character placement and along the way found and fixed some major precision
problems.  I don't care if your changes break consistency with prior results
(such consistency was always getting broken in any case).  Precision
problems for character stroke placement have long been my number one suspect
for why I could not get an absolutely clean comparisons for all examples
from one architecture/compiler to the next or from an old release to a new
one or from one front end to another.

But now that you have found and fixed the problems in the character code
where the precision was getting clobbered, I am sure the consistency in
results will be much improved, and any remaining precision problems (if they
exist) will be much easier to find.

Thanks for this big breakthrough, Maurice!

Alan
