/*!
\class Q3PointArray
The Q3PointArray class provides an array of points.
\compat
Q3PointArray is a QPolygon subclass that provides functions
to make it more source compatible with the \c QPointArray class
in Qt 3.
In Qt 4, we recommend that you use QPainterPath for representing
arcs, ellipses, and Bezier curves, rather than QPolygon.
*/
/*!
Sets the points of the array to those describing an arc of an
ellipse with size, width \a w by height \a h, and position (\a x,
\a y), starting from angle \a a1 and spanning by angle \a a2. The
resulting array has sufficient resolution for pixel accuracy (see
the overloaded function which takes an additional QMatrix
parameter).
Angles are specified in 16ths of a degree, i.e. a full circle
equals 5760 (16*360). Positive values mean counter-clockwise,
whereas negative values mean the clockwise direction. Zero degrees
is at the 3 o'clock position.
