drawTracks: detect antimeridian crossing by comparing consecutive screen X
positions against worldSize/2; use moveTo instead of lineTo on large jumps
so tracks don't draw a horizontal line across the globe.
Tgu2DMapView: replace the heuristic lon-range check (> 300°) with an exact
condition — skip bbox culling when the canvas is wider than the world tile
(entire globe visible) or when topLeft.lon >= bottomRight.lon (viewport
straddles the antimeridian). Both cases previously produced a nonsensical
bbox that hid polygons near ±180°.
drawRequests: remove per-polygon screen-space culling; viewport filtering is
already handled upstream by visiblePolygons, so the redundant check was
incorrectly hiding requests at high zoom levels near canvas edges.
