/* INTERNAL, PRIVATE definition of a PNG.
*
* The names chosen should be very close to the PNG specification, so
* consult that document for information about the meaning of each field.
* png_info is a modifiable description of a PNG datastream. The fields inside
* this structure are accessed through png_get_<CHUNK>() functions and modified
* using png_set_<CHUNK>() functions.
*
* With libpng < 0.95, it was only possible to directly set and read the
* the values in the png_info_struct, which meant that the contents and
* order of the values had to remain fixed. With libpng 0.95 and later,
* however, there are now functions that abstract the contents of
* png_info_struct from the application, so this makes it easier to use
* libpng with dynamic libraries, and even makes it possible to use
* libraries that don't have all of the libpng ancillary chunk-handing
* functionality. In libpng-1.5.0 this was moved into a separate private
* file that is not visible to applications.
*
* The following members may have allocated storage attached that should be
* cleaned up before the structure is discarded: palette, trans, text,
* pcal_purpose, pcal_units, pcal_params, hist, iccp_name, iccp_profile,
* splt_palettes, scal_unit, row_pointers, and unknowns. By default, these
* are automatically freed when the info structure is deallocated, if they were
* allocated internally by libpng. This behavior can be changed by means
* of the png_data_freer() function.
*
* More allocation details: all the chunk-reading functions that
* change these members go through the corresponding png_set_*
* functions. A function to clear these members is available: see
* png_free_data(). The png_set_* functions do not depend on being
* able to point info structure members to any of the storage they are
* passed (they make their own copies), EXCEPT that the png_set_text
* functions use the same storage passed to them in the text_ptr or
* itxt_ptr structure argument, and the png_set_rows and png_set_unknowns
* functions do not make their own copies.
* Some functions in libpng do directly access members of png_info. However,
* this should be avoided. png_struct objects contain members which hold
* caches, sometimes optimised, of the values from png_info objects, and
* png_info is not passed to the functions which read and write image data.
