Bugs

• loading order, land first, add importance to list.sort and renametiles
• pointInPolygon() does not always work, see Crystal Mountains
• rank 1,2 gridlines hit only sometimes, seems to always work at intersection with other geoms
• timepicker, arrow keys attempt string instead of numeric addition, until after first use of slider
• timeslider appears on startup even when history layer is disabled
• tile loading gets slower with every restart, until browser is cycled
• hilite of cities
  • sets moved true, redraws whole screen ?
  • hittest on close group of cities returns the wrong one
• hagstrand/lab is too big, move media out of git
