Can't call a function that as a side effect prints to std::cerr in
SAL_INFO. It will be called even if the log area doesn't match
$SAL_LOG. Just use only SAL_INFO and no plain std::cerr output. It's
fine to output a string with embedded newlines in SAL_INFO.

Also drop the debug output line with the glyph start positions, it was
less than useful.
