WG - Fill wedge
WG r,q1,qc(,qd)[;]
r ; Radius in user units or graphics units q1 ; Start point angle
qc ; Arc angle qd ; Chord angle
 Fill in a wedge centred on the current position with radius r , start point angle q1 , arc angle qc and chord
angle qd .
 After plotting, the cursor returns to its point of origin.
 Plotting is performed whether the pen is up or down.
 When scaling has been performed, the circle is plotted in user units.
 Also, when scaling has been performed, the value for r is a real number.
 When there is no scaling, the circle is plotted in graphics units.

When there is no scaling, the coordinate value for r is an integer number.
 The value for q1 is a clamped real number.
 When q1 is positive, the positive direction of the X axis relative to the current position is set at 0 degrees and
the start point is sought in the counterclockwise direction. The opposite occurs when q1 is negative: the
negative X axis is set at 0 degrees and the start point is sought by going clockwise.
 The value for qc is a clamped real number.
 Plotting proceeds counterclockwise when qc is positive and clockwise when it is negative.
 The value for qd is a clamped real number.
 When qd is not specified, the chord angle is the default value ( 5 degrees ).
