 Name:         »Elliptical pie« - Draw a filled elliptical arc 
               segment.

 Opcode:       11 (GDP 7)

 Syntax:       void v_ellpie ( int16_t handle, int16_t x, int16_t y, 
               int16_t xradius, int16_t yradius, int16_t begang, 
               int16_t endang );

 Description:  The call v_ellpie draws a segment of a filled 
               elliptical area ("pie segment"), such as those used for 
               pie-slice graphics. The following apply:

                Parameter  Meaning

                handle     Workstation identifier
                x          X-coordinate, and
                y          Y-coordinate of center point of arc
                xradius    Radius of X-axis
                yradius    Radius of Y-axis
                begang     Starting angle (in tenths of degrees 
                           0-3600)
                endang     Ending angle (in tenths of degrees 0-3600)

               Note: The fill attributes and the writing mode will be 
               respected during drawing, but the pixel size ratio will 
               be ignored. 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.
