NAME
       Font::TTF::Vmtx - Vertical Metrics
DESCRIPTION
       Contains the advance height and top side bearing for each glyph. Given the compressability of the data
       onto disk, this table uses information from other tables, and thus must do part of its output during the
       output of other tables
INSTANCE VARIABLES
       The vertical metrics are kept in two arrays by glyph id. The variable names do not start with a space
       advance
           An array containing the advance height for each glyph
       top An array containing the top side bearing for each glyph
METHODS
   $t->read
       Reads the vertical metrics from the TTF file into memory
   $t->out($fh)
       Writes the metrics to a TTF file. Assumes that the "vhea" has updated the numVMetrics from here
