Synopsis:
void fillellipse (int x, int y, int stangle, int endangle,
int xradius, int yradius);
(x, y) - center of the ellipse
stangle - starting angle
endangle - ending angle
xradius - radius of ellipse at x-axis
yradius - radius of ellipse at y-axis
Description:
fillellipse() draws an ellipse with current drawing color, then fills it with current fill pattern and current fill color.
