The png_set_option() function (and the "options" member of the png struct) was
added to libpng-1.5.15.
The library now supports a complete fixed point implementation and can
thus be used on systems that have no floating point support or very
limited or slow support. Previously gamma correction, an essential part
of complete PNG support, required reasonably fast floating point.
As part of this the choice of internal implementation has been made
independent of the choice of fixed versus floating point APIs and all the
missing fixed point APIs have been implemented.
The exact mechanism used to control attributes of API functions has
changed, as described in the INSTALL file.
A new test program, pngvalid, is provided in addition to pngtest.
pngvalid validates the arithmetic accuracy of the gamma correction
calculations and includes a number of validations of the file format.
