Bug evidence:

[x,y,z] = sphere(20);
hs=surf(x,y,z,'facecolor','y');
view(2)
axis equal
hl=light;
lightangle(hl,0,0)
% light is on -Y axis, thus at the
% bottom
rotate(hs,[0 0 1],30)
% rotate sphere to the right from 30°

It looks like the light has moved. This is due to a bug in rotate.m function. The "VertexNormals" property of the surf object is not updated as "xdata", "ydata" and "zdata" properties are.

This is fixed in the submitted version of rotate.m.
