v0.2.0

0.2.0 (2026-10-25)

Changed

• Breaking: m2DecomposeOutline refuses with m2_errorInvalid
  an outline whose pieces all fail validation, such as a triangle
  100 km long and 1 cm tall, where it returned m2_success with a
  count of 0. In both the fill and the measure call the count is left
  as it was, as for every refusal
  (#53).
• On AVX2 the solver's min and max are one instruction each, with the
  same bits. The pyramid bench scenes run faster on GCC 14 (best of
  nine rounds in each of two runs: pyramid15 8.1 and 8.9 ms before, 7.6
  and 7.8 ms after; pyramid30 57.7 and 59.7 ms before, 49.7 and 54.5 ms
  after), and every bench hash is unchanged.
  The library is also built with SSE math on 32-bit x86 and the
  compiler's default trapping math, from the family's shared flags
  (#56).

Fixed

• m2DecomposeOutline refuses a clockwise outline far from the
  origin. Its winding test summed the area in float, so near 98304 m a
  small clockwise hexagon summed positive and split into two pieces.
  The area is now summed in double
  (#53).
• Polygon validation accepts small polygons far from their body's
  origin. It summed the area for its thinness test in float, so
  m2MakePolygon refused every 0.25 m to 2 m box and right triangle at
  65536 m and 98304 m, most of them at 10000 m, and one at 1000 m.
  m2ComputeHull, the pieces of m2DecomposeOutline, the shape
  constructors, m2Shape_SetPolygon, m2World_ShatterBody and
  restore all go through the same check. The area is now summed in
  double, against the same threshold
  (#53).
• A body woken and put back to sleep before a step end, by a long step
  that moves it or by a teleport followed by m2Body_SetAwake(false),
  refreshes its contacts. It kept its old sleep streak, so its pairs
  kept the manifold from before the move: in the reproduction the
  contact points sat 0.4 m behind the box. The streak now starts from
  zero wherever a body is put to sleep
  (#51).
