Details:

Tick marks and outer grid lines are currently drawn above the axes outline.
See e.g.:


clf
axes ("xcolor", "r", "ticklength", [.1 .1], "linewidth", 4, "ygrid", "on",
"xgrid", "on")
box off


I'd be in favor of either drawing them before the axes outline (so that they
are hidden below) or not drawing outer ones(those at the limits) at all. The
latter solution is probably the best (no potential visual artifact due to
anti-aliasing in printout), but it has to take into account the presence of
the outline: in the above example we would like a tick mark at x=1 but not at
x=0 (same for the vertical grid line)
Any opinion?
