Visual offset attributes. Some items may have their location recorded in terms of
pairs of
offsets from their programmatically-determined location. The startho and endho attributes
record the horizontal offsets of the start and end points of the item, respectively.
Similarly, the startvo and endvo attributes record the vertical offsets of the start
and end
points of the item. The startto and endto attributes hold timestamp offsets, the most
common
use of which is as alternatives to the ho attributes.
