chipmunk pro 7.0 questions

[dugbug]

There are a ton of API changes. I understand the docs are not ready yet. Some of them are obvious (x.pos became x.position) but chipmunkExtras.h has been neutered in this release (presumably absorbed?) and a lot of support APIs I cannot find such as
[body resetForces]
[body isRogue]

Also just to check I assume body.affineTransform from chipmunkExtras became just body.transform.

reset forces used to zero out force and torque. Im not sure if this fully replicates that API but is this ok:
body.force = cpvzero;
body.torque=0.0;

isRogue was used to see if a body was in a space or not. I used it to sanity-check some stuff. Can we just test the space attribute for nil?
body.space

Then there is [space addBounds] which signature has changed quite a bit. Why not use CGRect anymore? At least provide a convenience routine.

Also, how do I interpret cpContactPointSet? It used to look like this:

struct {
/// The position of the contact point.
cpVect point;
cpVect normal;
cpFloat dist;
} points[CP_MAX_CONTACTS_PER_ARBITER];

and now looks like this:

struct {
/// The position of the contact on the surface of each shape.
cpVect pointA, pointB;
cpFloat distance;
} points[CP_MAX_CONTACTS_PER_ARBITER];

I want the position of the contact point per the old API. Is "pointA" that point?

Figured the addBounds question. This is how to convert cgrect to cpBB and what to do with filter vs layers/group:

cpBB bds;
bds.l = bounds.origin.x;
bds.r = bounds.origin.x + bounds.size.width;
bds.b = bounds.origin.y;
bds.t = bounds.origin.y + bounds.size.height;
[space addBounds:bds
thickness:1000.0f
elasticity:1.0f
friction:1000.0f
filter:CP_SHAPE_FILTER_ALL
//layers:CP_ALL_LAYERS
//group:CP_NO_GROUP
collisionType:borderType];
