* WebGLRenderer.config has a new property `maxTextures` which is derived from `gl.MAX_TEXTURE_IMAGE_UNITS`, you can get it via the new method `getMaxTextures()`.
* WebGLRenderer.config has a new property `maxTextureSize` which is derived from `gl.MAX_TEXTURE_SIZE`, you can get it via the new method `getMaxTextureSize()`
* WebGLRenderer has a new property `compression` which holds the browser / devices compressed texture support gl extensions, which is populated during `init`.
### Bug Fixes
* The Script File type in the Loader didn't create itself correctly as it was missing an argument (thanks @TadejZupancic)
* The Plugin File type in the Loader didn't create itself correctly as it was missing an argument.
* WebAudioSoundManager.unlock will now check if `document.body` is available before setting the listeners on it. Fixes old versions of Firefox, apparently. #3649 (thanks @squilibob)
