=head1 NAME
Font::TTF::Sill - Graphite language mapping table
=head1 DESCRIPTION
=head1 INSTANCE VARIABLES
=over 4
=item version
Table version number.
=item langs
Contains a hash where the key is the language id and the value is an array of
language records
=back
=head2 Language Records
Each language record is itself an array of two values [fid, val]. fid is the
feature id and is held as a long.

=head2 $t->minsize()
Returns the minimum size this table can be. If it is smaller than this, then the table
must be bad and should be deleted or whatever.
