#include <Quickdraw.h> Quickdraw
void PaintOval(theRect );
Rect *theRect ; rectangle defining oval's position and size
PaintOval draws and fills an oval that fits just inside a specified rectangle.
If the rectangle is a square, the oval will be circular. The figure is drawn in
the current pen pattern and transfer mode.
theRect is the address of an 8-byte Rect structure, defined in local
coordinates.
Returns: none

PaintOval doesn't change the pen positon.
This function overwrites the entire interior of the oval, including any
pixels colored by a previous call to FrameOval.
As with all Quickdraw drawing, the output is clipped to the intersection of
the current GrafPort's BitMap boundary rectangle, the port rectangle,
clipping region, and visible region.
