Why does "mesh " set surface "facecolor" to "none"?

[Michael Goffioul]

Matlab sets it to [1 1 1] by default, which looks better.

Other remarks concerning "mesh":
1) axes properties ("view") should only be changed if the axes object
is not in hold mode (that is gca.nextplot is not "add")
2) box should be disabled and grid should be enabled (again only in
non-hold mode)

The above remarks actually applies to any standard function producing
3D plots (surf, mesh, bar3...).

Michael.
