<descr>
<p>
<var>AngleArc</var> is a method used to draw an arc over a specified angle
along the circumference of a circle with given radius and center point.
</p>
<p>
<var>X</var> and <var>Y</var> contain the coordinates for the center of the
circle along which the arc is drawn.
</p>
<p>
<var>Radius</var> is the distance from the center point of the circle to the
circumference where the arc is drawn. The LongWord type can contain positive
integer values in the range 0..4294967295.
</p>
<p>
<var>StartAngle</var> and <var>SweepAngle</var> indicate where the arc is
drawn on the circumference of the circle. The angle values are specified in
degrees.
</p>
<p>
StartAngle contains the angle from the center of the circle to the starting
point on the circumference. Its value is relative to the X-Axis and
increments in the counter-clockwise direction.
</p>
<p>
SweepAngle defines the length of the arc expressed in degrees, and is
used to find the ending point for the arc. Its value is relative to the
starting point, and increments in the counter-clockwise direction.
</p>
<p>
Before the arc is drawn, LineTo is used to drawn a line from the current pen
position to the starting point of the arc.
</p>
<p>
The Arc method is called to render the arc using the center point, radius,
starting point, and ending point values.
</p>
<p>
After the arc is drawn, the Pen position is moved to the ending point for the
arc.
</p>
<p>
Update values for the Pen style, mode, color or width prior to calling the
method.
