Detailed Description

Singleton cache mapping connection IDs to Bezier control points.

Typical usage:

auto& cc = ConnectionCache::Get();
if (!cc.HasCached(connId))
{
    BezierPoints pts = ComputeBezier(src, dst);
    cc.SetBezier(connId, pts);
}
const BezierPoints& pts = cc.GetBezier(connId);
DrawBezier(pts);
