 Name:         »Pie-slice« - Draw a filled circular "pie-slice" 
               segment.

 Opcode:       11 (GDP 3)

 Syntax:       void v_pieslice ( int16_t handle, int16_t x, int16_t y, 
               int16_t radius, int16_t begang, int16_t endang );

 Description:  The call v_pieslice draws a filled circular arc, such 
               as used in pie-slice graphics, for instance. The 
               following apply:

                handle     Workstation identifier
                x          X-coordinate, and
                y          Y-coordinate for the centre point
                radius     Radius in x-coordinate units
                begang     Start angle (in tenths of degrees 0-3600)
                endang     End angle (in tenths of degrees 0-3600)

               Note: The fill attributes and the writing mode will be 
               respected during drawing. The angle is specified in 
               1/10 degree and anticlockwise:

 Return value: The function does not return a result.

 Availability: Supported by all drivers. This function comprises one 
               of the 10 VDI GDP's (Generalized Drawing Primitives). 
               Although all current drivers support all GDP's, their 
               availability is not guaranteed and may vary. To check 
               for a particular GDP refer to the table returned by 
               v_opnvwk or v_opnwk.
