Utility functions for AAT tables

## NAME

Font::TTF::AATutils - Utility functions for AAT tables

### ($classes, $states) = AAT\_read\_subtable($fh, $baseOffset, $subtableStart, $limits)

### $length = AAT\_write\_state\_table($fh, $classes, $states, $numExtraTables, $packEntry)

`$packEntry` is a subroutine for packing an entry into binary form, called as

`$dat` = `$packEntr`y($entry, `$entryTable`, `$numEntries`)

where the entry is a comma-separated list of nextStateOffset, flags, actions

### ($classes, $states, $entries) = AAT\_read\_state\_table($fh, $numActionWords)

### ($format, $lookup) = AAT\_read\_lookup($fh, $valueSize, $length, $default)

### AAT\_write\_lookup($fh, $format, $lookup, $valueSize, $default)
