Change most places we control (i.e not helper libs) to use SGPath
to represent a path, instead of using std::string. Extend SGPath
API to explicitly expose the path in either UTF-8 or the
system 8-bit encoding.
Adapt the freealut code into a WAV-file reader. As a side-effect, it would now be possible to deploy WAV files compressed with gzip, since we use ZLib's gzread functions to read from disk.
Make sg_throwable inherit from std::exception.
change exception objects to contain C strings: exception objects should not
include objects, like std::string, whose copy constructor could throw.
There are constructors for sg_io_exception that don't initialize the
location. In this case getFormattedMessage does still output an extra
line with " at" followed by ... nothing. Looks silly.
