Each pin holds a keyed focus handle of its own, a Tab stop and pressable
while its place is in view, so a focused pin that pans out of view keeps
focus and the arrows go on panning, and a popup that scrolls away hands
focus back to its pin wherever it lies. A popup whose place is off view
takes no focus. Tests hold the tall card's cap and scrolling body, the
map staying under its wheel, and markers refuse a repeated key.

A pin whose place lies outside the view takes no press or Tab, as its
popup would not show. The popup takes focus when it shows and, the
frame it stops showing by its button, Escape, the owner or a pan, hands
focus back to what held it, so focus stays in the map. Its body scrolls
past the room on its side and it paints over the zoom buttons. Tiles
load through gpui's logging loader, so a tile that fails says so. A
drag's owner check has a test, and the per-move viewport logs at debug.
The maps tests split into the map's and the popup's.

maps::MapView lays the host's tile for each zoom, column and row in Web
Mercator, the nearest cut scaled past the zooms it serves, on whole
pixels. gpui packs pictures in its atlas without padding and samples
them linearly, so each tile draws with a one-pixel rim copied from its
own edge, one of its pixels larger each side and clipped, and no seam
shows. A drag, the wheel or the arrows pan; Command-wheel, + and - or
its buttons zoom about the pointer or the center; the owner keeps the
viewport. MapMarker pins take a press and Enter when the map hears
them; MapPopup opens toward the map's larger half and stays inside it,
closing by its button or Escape. LocationPicker picks the place under a
center crosshair; CoordinateDisplay writes degrees or degrees, minutes
and seconds with tabular figures and a copy button. The gallery's tiles
are Natural Earth's countries, cut z0 to z3 by scripts/tiles.py.
