2018-08-18Remove top-level const from function-scope variablesCosmin Truta
As per the const correctness rules, top-level const-ness of data in automatic scopes does not propagate outside of these scopes (unlike const-ness at lower levels, such as pointers to const data). Previously, const was used liberally, but inconsistently across the libpng codebase. Using const wherever applicable is not incorrect. However, _consistent_ use of const is difficult to maintain in such conditions. In conclusion, we shall continue to use const only where doing so is strictly necessary: 1. If a function guarantees that it will not modify an argument passed by pointer, the corresponding function parameter should be a pointer-to-const (const T *). 2. Static data should not be modified, therefore it should be const. Reference: Google C++ Style Guide https://google.github.io/styleguide/cppguide.html#Use_of_const
2018-08-18Replace the remaining uses of PNG_CONST with constCosmin Truta
In v1.6.0, compiler support for const became a requirement. It should be used consistently. To maintain backwards compatibility, PNG_CONST is still maintained in deprecated form.

2018-06-17[libpng16] Replace the remaining uses of png_size_t with size_tCosmin Truta
In v1.6.0, size_t became a required type. It should be used consistently. To maintain backwards compatibility, png_size_t is still maintained in deprecated form.
