* Replaced push_back calls with emplace_back where applicable. * Replaced size() == 0 and size() != 0 with empty() and !empty(). * Replaced C style loops for range for loops where applicable. * Fixed mismatching arg names between function declarations and definitions. * Replaced NULL and 0 (in the context of pointers) with nullptr. * Remove unnecessary calls to string::c_str() where applicable. * Replaced deprecated C headers with proper C++ headers. * Removed unnecessary null pointer checks when deleting pointers (deleting a null pointer has no effect). * Fixed a potential memory leak in apngloader.cpp file. * Replaced unsafe strcpy with strncpy in the demangle_name function.
