Converts the given place in the view coordinate system to the nearest representative location in the model.

Parameters:
t - the text component for which this UI is installed

Provides a mapping from the view coordinate space to the logical coordinate space of the model.

Parameters:
t - the text component for which this UI is installed
pt - the location in the view to translate. This should be in the same coordinate system as the mouse events.
biasReturn - filled in by this method to indicate whether the point given is closer to the previous or the next character in the model

This implementation calls viewToModel(t, new Point((int) pt.getX(), (int) pt.getY()), biasReturn).
Parameters:
t - the text component for which this UI is installed
pt - the location in the view to translate.
biasReturn - filled in by this method to indicate whether the point given is closer to the previous or the next character in the model
