Sets the selection to the range specified
by the given point, where the x coordinate
represents the start index and the y coordinate
represents the end index.
<p>
Indexing is zero based. The range of
a selection is from 0..N where N is
the number of characters in the widget.
</p><p>
Text selections are specified in terms of
caret positions. In a text widget that
contains N characters, there are N+1 caret
positions, ranging from 0..N. This differs
from other functions that address character
position such as getText () that use the
usual array indexing rules.
