v1.1.0

Activity density heatmaps

View → Activity heatmap shows where activities of a chosen type concentrate
along the road network — home, work, school, and whatever else the scenario
defines.

Density is measured along the roads, not in straight lines. Two houses on
opposite banks of a river are far apart even when they look adjacent, and a
motorway that runs past housing with no nearby exit stays dark, because nobody
can reach it from there.

• Maps are cached per scenario, and precomputed in the background on smaller
  networks so the first click is instant
• Types can share one colour scale so they can be compared, or each can use its
  own — View → Compare types on one scale
• Colours are anchored at the 99th percentile, so a handful of extreme road
  segments cannot wash out the rest of the map
• The legend now appears in exported PNG and PDF images, not only on screen
• Computation runs off the UI thread and stops cleanly when the scenario
  changes or the window closes

Measured on a 275K-node, 635K-link metro network with 1.3M activities: 1–13
seconds per map depending on the activity type. A 92K-link scenario computes
all seven types in under half a second.

Activity markers now use the real locations

MATSim actstart/actend events carry each activity's own coordinates, but
these were being discarded and positions derived from the endpoint link's
to-node instead — a median 125 m off, up to 1058 m.

This also fixes two display bugs in the agent plan overlay:

• Every person's first activity of the day was invisible, because it has no
  preceding leg to hang a marker on
• Two distinct activities of the same type could merge into one marker when
  their positions snapped to the same node

Other

• Background map tile services now carry their required attribution
• Build scripts recover automatically from a stale CMake cache
• Per-activity-type counts are logged after event parsing

Note: the events cache format has changed. Existing .vidx files are
rebuilt automatically on first load.
