The Anchor defines an anchor point on a glyph providing various information depending on how much is available, including such information as the co-ordinates, a curve point and even device specific modifiers.

# INSTANCE VARIABLES

x
| XCoordinate of the anchor point
y
| YCoordinate of the anchor point
p
| Curve point on the glyph to use as the anchor point
xdev
| Device table (delta) for the xcoordinate
ydev
| Device table (delta) for the ycoordinate
xid
| XIdAnchor for multiple master horizontal metric id
yid
| YIdAnchor for multiple master vertical metric id

# METHODS

## new

Creates a new Anchor

## read($fh)

Reads the anchor from the given file handle at that point. The file handle is left at an arbitrary read point, usually the end of something!

## out($fh, $style)
