Minimap Points of Interest

Declares points of interest: a position, a shape, a tint and a name, drawn on the minimap and on the full-screen world map.

Marker shapes are a small fixed set — dot, ring, star, cross, flag, house, skull and the default icon. A shape is a font, and its ascent is what tells the shader which one it is drawing, so the set is bounded by the renderer's budget rather than by taste.

Markers past maxMinimapMarkers are clipped by priority and the clipping is reported, rather than dropped silently.
