> - TclMagick/unix/m4/tcl.m4: Update tcl.m4 to TEA 3.10. File supplied by Massimo Manghi.

> - coders/png.c: Added support for a proposed new PNG chunk (exIf read-write, eXIf read-only) that is currently being discussed on the png-mng-misc at lists.sourceforge.net mailing list.

> - coders/png.c: Added read_user_chunk_callback() function and used it to implement a private PNG caNv (canvas) chunk for remembering the original dimensions and offsets when an image is cropped. Previously we used the oFFs chunk for this purpose, but this had potential conflicts with other applications that also use the oFFs chunk.

> - TclMagick/Makefile.am (AM_DISTCHECK_CONFIGURE_FLAGS): Applied patch by Massimo Manghi to set AM_DISTCHECK_CONFIGURE_FLAGS so that 'make distcheck' remembers configuration options, and also to uninstall pkgIndex.tcl.
> - magick/image.c (SetImageEx): Use PixelIterateMonoSet() for possibly improved efficiency.
> - magick/pixel_iterator.c (PixelIterateMonoSet): New pixel iterator intended for use when initializing image pixels, without regard to existing values.
