[Maxima] enhanced3d and implicit plot

[Jerónimo Alaminos Prats]

Can someone check if this is working in maxima 5.19?

load(draw);
eq:x^2+y^2+z^2=1;
draw3d(enhanced3d=true,
		implicit(eq,x,-1,1,y,-1,1,z,-1,1))

I get the plot but no colors at all. It is working in version 5.18.1.
Thank you,
Jerónimo.
