<H3>Description</H3>
<P>Returns the weighted average color between the two colors.
The red, green, and blue values are averaged using the following
formula:
<UL><PRE>
color = c1 * weight + c2 * (1 - weight)
</PRE></UL>
<P>Thus, a <CODE>weight</CODE> value of 1.0 will return the
first color, while a value of 0.0 will return the second color.
