Font::TTF::Hdmx - Horizontal device metrics
The table consists of an hash of device metric tables indexed by the ppem for that subtable. Each subtable consists of an array of advance widths in pixels for each glyph at that ppem (horizontally).
Individual metrics are accessed using the following referencing:
In addition there is one instance variable:
Number of device tables.
Reads the table into data structures
Outputs the device metrics for this font
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.
For each subtable it calls &sub($ref, $ppem)
Outputs device metrics a little more tidily
