Stack markers by the shared draw order - #32

Conversation
Markers were ranked by (zIndex, add order); they now rank by MarkerDrawOrder, so equal zIndex puts the southern (then western) marker on top regardless of add order. Shapes keep their (zIndex, add order) ranking.
Same-zIndex markers follow the screen position (lower in front). The stack order is rebuilt in one pass with ArcGISGraphicsZIndex.replaceAll.

Summary
Feed this provider's native marker order from the shared
MarkerDrawOrderhelper (core PR), so markers stack the same way on every provider:zIndex ?? 0in front;Depends on the core
fix/marker-zindex-orderPR.Verification
Two overlapping markers with equal zIndex (north/south), plus a
zIndex: 1marker added first vs a null-zIndex marker added last. Rotating 0° → 180° without re-adding brings the north marker to the front; zIndex 1 stays in front at every heading.Commits
