-+ * Copyright (C) 1998-2002,2006-2008 Glenn Randers-Pehrson (glennrp@users.sf.net)
-+ * Copyright (C) 2005 Greg Roelofs
-+ *
-+ * The most recent version of pngcrush can be found at SourceForge in
-+ * http://pmt.sf.net/pngcrush/
-+ *
-+ * This program reads in a PNG image, and writes it out again, with the
-+ * optimum filter_method and zlib_level. It uses brute force (trying
-+ * filter_method none, and libpng adaptive filtering, with compression
-+ * levels 3 and 9). It does the most time-consuming method last in case
-+ * it turns out to be the best.
-+ *
-+ * Optionally, it can remove unwanted chunks or add gAMA, sRGB, bKGD,
-+ * tEXt/zTXt, and tRNS chunks. It will remove some chunks such as gAMA,
-+ * cHRM, pHYs, and oFFs when their data fields contain all zero, which is a
-+ * mistake.
-+ *
-+ * Uses libpng and zlib. This program was based upon libpng's pngtest.c.
-+ *
-+ * Thanks to Greg Roelofs for various bug fixes, suggestions, and
-+ * occasionally creating Linux executables.
-+ *
-+ * Thanks to Stephan Levavej for some helpful suggestions about gcc compiler
-+ * options and for a suggestion to increase the Z_MEM_LEVEL from default.

-+
-+/* To do:
-+ *
-+ * Reset CINFO to reflect decoder's required window size (instead of
-+ * libz-1.1.3 encoder's required window size, which is 262 bytes larger).
-+ * See discussion about zlib in png-list archives for April 2001.
-+ *
-+ * Add a "pcRu" ancillary chunk that keeps track of the best method,
-+ * methods already tried, and whether "loco crushing" was effective.
-+ *
-+ * Try both transformed and untransformed colors when "-loco" is used.
-+ *
-+ * Check for unused alpha channel and ok-to-reduce-depth.
-+ * Take care that sBIT and bKGD data aren't lost when reducing images
-+ * from truecolor to grayscale.
-+ *
-+ * Rearrange palette to put most-used color first and transparent color
-+ * second (see ImageMagick 5.1.1 and later).
-+ *
-+ * Finish pplt (partial palette) feature.
-+ *
-+ * add "-time" directive
-+ *
-+ * Allow in-place file replacement or as a filter, as in
-+ * "pngcrush -overwrite file.png"
-+ * "pngcreator | pngcrush > output.png"
-+ *
-+ * Use an alternate write function for the trial passes, that
-+ * simply counts bytes rather than actually writing to a file, to save wear
-+ * and tear on disk drives.
-+ *
-+ * Remove text-handling and color-handling features and put
-+ * those in a separate program or programs, to avoid unnecessary
-+ * recompressing.
-+ *
-+ * Move the Photoshop-fixing stuff into a separate program.
-+ *
-+ * GRR: More generally (superset of previous 3 items): split into separate
-+ * "edit" and "crush" programs (or functions). Former is fully libpng-
-+ * aware, much like current pngcrush; latter makes little or no use of
-+ * libpng (maybe IDAT-compression parts only?), instead handling virtually
-+ * all chunks as opaque binary blocks that are copied to output file _once_,
-+ * with IDATs alone replaced (either by best in-memory result or by original
-+ * _data_ resplit into bigger IDATs, if pngcrush can't match/beat). "edit"
-+ * version should be similar to current code but more efficient: make
-+ * _one_ pass through args list, creating table of PNG_UINTs for removal;
-+ * then make initial pass through PNG image, creating (in-order) table of
-+ * all chunks (and byte offsets?) and marking each as "keep" or "remove"
-+ * according to args table. Can start with static table of ~20-30 slots,
-+ * then double size & copy if run out of room: still O(n) algorithm.
