LXELIP(ix.i2.r, iy.i2.r, iwidth.i2.r, ihght.i2.r, istrt.i2.r,
This routine draws an ellipse on the LX color graphics display window
with center at (IX,IY), with a width of IWIDTH, a height of IHGHT,
starting at ISTRT and extending for IEXTNT measured in 64ths of
degrees from 3 o'clock in the counterclockwise direction and color
code of KOLOR. See the descriptions of the LXPNT and LXMODE routines
for information on how color codes are used. The ellipse will be
filled or unfilled depending upon the most recent call to LXRCMD.
