1.3.7

A bugfix release, mostly for the minimap.

• Town borders were misaligned if you had changed the minimap zoom. The mod read Xaero's zoom backwards, so at anything other than the default zoom level the overlay was drawn at the wrong scale and pulled in toward the middle of the minimap. This also fixes minimap waypoint positions in cave mode.
• The overlay stayed north-up on a large circular minimap instead of turning with the terrain.
• Town borders on the minimap were glitchy: outlines could be drawn with a side missing, some towns lost their border entirely, and which ones broke changed as you walked. Two separate causes, both fixed.
• The town overlay could vanish completely on a large minimap zoomed out. It now draws what fits instead of nothing.
• False borders were drawn along the edge of the visible area where a town continued past it.
• Xaero updates can no longer crash the game. If a future Xaero version changes something the mod hooks into, that one feature stops working instead of the game failing to start.
• Fixed a memory leak where player heads were kept forever, and a custom overlay file being discarded entirely because of a single bad coordinate.
