Description: Cannot build fontforge 20090923 with libpng 1.4
when run fontforge, there is warning like fontforge is built with libpng 1.2.xx but run with libpng 1.4

Additional info:
* libpng 1.4
* fontforge 20090923


Steps to reproduce:
As in libpng 1.4, The png_struct and info_struct members "trans" and "trans_values" were
changed to "trans_alpha" and "trans_color", respectively.
http://www.libpng.org/pub/png/libpng-manual.txt

Then fontforge cannot be built again.
There is no upstream fix, here is an ugly but worked patch.

   libpng14.patch (0.5 KiB)

Reason for closing:  Fixed
Additional comments about closing:  fixed in fontforge-20090923-2. dlopen was disabled and python interpreter was added.

And another rebuild missed thanks to the use of dlopen(). Note that simple rebuilding will not fix PNG functionality, as the dlopen code makes wrong assumptions for the library name.

how to build with ``--with-regular-link''? Then fontforge will link with libpng, not dlopen libpng.
i suggest to build with python support, fontforge script is like perl, but python programmer seems more easy.
