However, using the terrain-only grid reveals one discrepancy between the
short pathfinder (which uses unit radii) and the long one (which uses
unit clearances). So I implemented the change proposed by sanderd17 in
#3294, which is removing unit radius and using only the pathfinder
clearance. Refs #3294
Now some tweaking has to be done in the templates, so that units get a
passability class suited to their apparent size. In the meantime the
unit motion is quite bugged.
This was SVN commit r16867.
Cast to smaller integer types explicitly.
Generally avoid platform-dependent types (size_t) in simulation code.
Use float versions of math.h functions, not double.
This was SVN commit r10017.
Pass terrain passability data to AI scripts.
Expand pathfinder passability data to 16 bits per tile, to allow more
classes.
Support 16-bit ints in serializer.
Partially support JS typed arrays.
Allow foundations to be placed on top of units (fixes#499).
Stop farms and fishes blocking movement (fixes#534).
Add obstruction flags to allow finer control over what they block.
Associate entity IDs with obstruction shapes, to allow finding colliding
entities.
Support moving to the edge of a target entity with inactive obstruction.
Support foundation entities in AI.
Support playing as non-hele civs.
This was SVN commit r8899.
Support asynchronous path queries.
Allow escaping when stuck in impassable terrain tiles.
Split Update message in multiple phases, to cope with ordering
requirements.
Support automatic walk/run animation switching.
This was SVN commit r8058.

Simplify range query result ordering.
Avoid throwing exception on script errors in debug serializer.
This was SVN commit r7828.
Add short-range vertex-based pathfinder.
Integrate new pathfinder into unit motion code.
Change obstruction system to get rid of circles, and differentiate
structures from units.
Make PositionChanged messages synchronous.
Try to prevent some accidental float->int conversions.
This was SVN commit r7484.
