Gather all points inside the given sphere. Radius is assumed to be small, so we don't bother culling the cells.

Get the byte order of the system.

Get weak proxy.

Returns true if any of the charts can grow more.

Hints.

@@ Test this!

Only the actual object should call this.

Handle assertion through the assert handler.

Parse triples: i, i/j/k, i//k, i/j

a quick hack to only allow decoding some of a PNG... I should implement real streaming support instead

Triangulate polygon and sum triangle areas.

after we see SOS

Computes the coordinates of the vertices of a triangle in a local 2D orthonormal basis of the triangle's plane.

Decrease reference count and remove when 0.

Relinquish ownership of the underlying pointer and returns that pointer.

Note that this hash does not handle NaN properly.
