.SH NAME
xarc - draw a part of an ellipse
.SH CALLING SEQUENCE
.nf
xarc(x,y,w,h,a1,a2)
.fi
.SH PARAMETERS
.TP 9
x,y,w,h
: four real values defining a rectangle.
.TP
a1,a2
: real values defining a sector.
.SH DESCRIPTION
\fVxarc\fR draws a part of an ellipse contained in the rectangle
\fV(x,y,w,h)\fR (upper-left point, width, height), and in the sector
defined by
the angle \fValpha1\fR and the angle \fValpha1+alpha2\fR.
\fValpha1\fR and \fValpha2\fR are
given respectively by \fVa1/64\fR degrees and \fVa2/64\fR degrees.
This function uses the current graphics style and scale.
