Added dvipng subroutine. Corrected some errors in math2image. dvipng
is still not being called correctly -- I think math2image needs more
updates.
dvipng is also in IO.pm, but making this available to WeBWorK1.8 seems
like a lot of work, hence I've only made a copy of the dvipng subroutine
from IO.pm. With luck this will not interfere with WeBWork2.0. I'm
open to suggestions for a better way to make both dvipng methods
available to both WeBWorK2.0 and WeBWorK 1.8

Made modifications to the tth subroutine that make it work
seomewhat better with matrices. There is a filter, which
changes the characters used by tth that only works properly
with iCAB (not much use). I have also added the -u switch
to tth which makes the symbols work well with
MSIE, OmniWeb, iCab, and Safari on the Mac. It does not work
with Camino on the mac, but it does work with Mozilla.
How does it work in your browser?

Commented out subroutines which are not being used (to the best

originally designed to help clean up the instructors answers. This

We might want to return to this problem later.

Fixed bug in PGcomplexmacros.pl having to do with the lack of a
=cut line in the pod documentation.
The loadMacros eval doesn't fail gracefully when this kind of mistake
occurs. More work needs to be done on loadMacros.
Also changed the _PGcomplexmacros_init subroutine to include the
exporting of variables from Complex.
I think this is what it was supposed to do in any case, but perhaps not.
When using the forking process it was only necessary to export the
variables in the parent.

Added documentation and _PG....macros_int functions to these files.
In PGcomplexmacros.pl I removed the automatic exportation of log() from
PGcomplexmacros.pl since
this (and sqrt() ) cause conflicts with CORE::log() and CORE::sqrt().
-- Warnings of the form "Ambiguous call to ..... resolved in favor of
CORE::... " etc.
The functions can always be accessed by Complex::log() and Complex::sqrt()
when needed for complex numbers.
There may be a more sophisticated method of exporting these calls which
would avoid the warnings and remain transparent both to those who are
using complex numbers and those who are not. If anyone has any ideas they
will be welcome. The code to modify is at the top of the
PGcomplexmacros.pl file inside the _PGcomplexmacros_init subroutine.

Modifications in these two files make questions whose answer blanks hve
the same names behave properly.
The new versions of CGI seem to return such answers as a reference to an array.
Earlier versions returned the answrs as a string with \0 separators.
With the new changes the AnswerEvaluator get_student_answer subroutine and
the NAMED_ANS_RULE in PGbasicmacros.pl will handle either a null separated
string or an answer array when dealing with vector answers.
This should correct some difficulties experienced in the linear algebra
questions. More testing needs to be done.

Made sure that num_cmp, fun_cmp and str_cmp return an
answer evaluator when used in scalar context. In other words
$ans_eval = num_cmp(234);
will now work as expected -- you will get one answer evaluator which
checks whether the answer is 234.
Previously you had to write:
($ans_eval) = num_cmp(234);
or else you would have the numeral 1 placed in $ans_eval since
that is how many answer evaluators were created.
