This allows overlays to request draw after any interface or layer. This
allows removal of the ABOVE_MAP layer which can now just be replaced
with requesting draw after the map interface. This also fixes item
overlays from drawing over top of the map by now drawing the item
overlay immediately after the interface and/or layer the item is on is
drawn.
For backwards compatability, ABOVE_WIDGETS is kept as a layer, but
internally just requests draw after the 3 TLIs.
Due to overlays defaulting to the UNDER_WIDGETS layer, a new layer
MANUAL has been added, which is intended for use when requesting draw
after specific interfaces or layers, so that the overlay is otherwise
not drawn a second time due to being UNDER_WIDGETS.
The rendered x/y position of the viewport layer is the same as the viewport offsets. This also no longer assumes the x/y offets are the same, even though in practice they always are.
The returned widget isn't actually the viewport widget, but is a layer within the viewport, and only needs to be used within the overlay renderer to position the snapcorners
Adds a panel which tracks damage dealt to Zalcano's health and shield
to make it easier prioritising what to focus on at a low level.

This removes the hack of double setting the widget position in
WidgetOverlay, which was required to override the overlay renderers
clamping code in both overlay drag and in overlay rendering.
Requiring the mouse to be moved first causes dead clicks when the mouse is
pressed immediately after entering overlay management mode. Also since
resetOverlayManagementMode() clears the managed overlay, after dragging
an overlay it again requires the mouse to be moved to pick up a click on it
if dragging again or trying to reset the overlay.
