build/Three.js - Includes all renderers + extras build/custom/ThreeCanvas.js - Canvas renderer only build/custom/ThreeDOM.js - DOM renderer only build/custom/ThreeSVG.js - SVG renderer only build/custom/ThreeWebGL.js - WebGL renderer only build/custom/ThreeExtras.js - Extras only Moved `THREE.Detector.js` to `examples/js/Detector.js`. Updated examples to reflect these changes.
