Water Ripple Control Magnifier for Pen Machines or User Assistance

      A method for enlarging only those elements of a user interface
that a user can directly interact with, using a pen or mouse, is
disclosed.

      The solution allows a user to define a perimeter around the
mouse or pen pointer, that will magnify those elements on the user
interface that are mouse or pen sensitive.  For example, if the
user's pointer moves over the push buttons on a slider, the slider
shaft (which falls within the area surrounding the pointer) and the
buttons to modify the slider are magnified, but the user text that is
not modifiable or user-input sensitive is left the normal size.

      Sample algorithm - The user defines, through a desktop or other
global settings location, the perimeter surrounding the pen or mouse
pointer that will be sensitive to enlargement.  The user also
determines the extent to which the user-input sensitive controls will
be magnified.

      The desktop is drawn as it would normally be drawn.  Then the
area around the user's pointer is queried for input sensitive
controls.  These controls are placed at the end of the drawing list
in such a manner that they will be magnified as specified.  This will
not interfere with the calculation of the control that receives the
input under the user's pointer, as the coordinates and magnification
for the specific point under the user's pointer is not changed.
