* contrib/hbhpdf/3rd/libhpdf/hpdfimap.c
* contrib/hbhpdf/3rd/libhpdf/libhpdf.dif
+ patched to build with libpng 1.6 w/o warning
identical to this upstream patch:
f1817baea4
* bin/commit.hb
! fixed to add shebang to newly created commit hook
* bin/check.hb
! exclude maskimag.png from processing
! typo in png processor name
! minor syntax clarification
* contrib/hbhpdf/tests/files/maskimag.png
! restored original version, as any optimized version will
cause libharu to GPF (visible when running the demo)
