Okay, I guess when they say "Z-sorting" they aren't kidding
around.  It works great if you are looking straight down the Z
axis.

BUT, if you are trying to create an elevated view (looking down at an
angle on a playfield, kind of like looking at a football field from
the stands), objects that are above (more along the -Y axis), but are
a little farther behind (more along the +Z axis), get drawn before
items that are below and in front of them.  There are cases when this
is not correct for the view, the "-Y" position *should* cause the item
to appear in front of an objects that is closer to the viewpoint
in the Z axis.

Is there any way to adjust for this anomoly?  It would be nice if
GsSortObject4() "knew" about the view and automatically compensated.

Any ideas?
