/***************************************************
OnToolHitTest
The framework calls this member function to determine whether a point is in
the bounding rectangle of the specified tool. If the point is in the
rectangle, it retrieves information about the tool.
Params:
point - please see MSDN for more information on the parameters.
pTI
Returns:
If 1, the tooltip control was found; If -1, the tooltip control was not found.
