Fix compilation problem -- shouldn't return m_file as a bool, use m_file.good() instead.
RLA output did consider BitsPerSample properly
oiiotool --no-autopremult, --autopremult
Turns off (or no) auto premultiplication for subsequent input images.
Better exception safety in scan_for_matching_filenames.
More robust to malformed patterns.
maketx: --attrib, --sattrib, --sansattrib (works like oiiotool)
Better error message for unmatched file sequence wildcards
Test of Strutil::format() presision -- bug disabled
fix int type from last checkin
OpenEXR output string array fix
Eew, it was pulling the data assuming it was a std::string*, but actually
they are just char**'s.
Improved ordering of channels for EXR files.

Now we very robustly cluster "layers" together (with the unnamed layer
first, if it exists), and within each layer have a canonical RGBAZ
order.
