If you set window.FORCE_WEBGL or window.FORCE_CANVAS in the window in which the Phaser game is loaded it will over-ride the renderer type setting in your game config, and force either WebGL or Canvas. This is handy for quickly testing the differences between renderers without having to do a new build each time.

 * The `ParticleEmitterManager` now has the Transform component. This means you can now set the position, rotation or scale of the Emitter Manager, and it will influence every Emitter it is rendering. The Managers transform is mixed with that of the Camera. This works in both Canvas and WebGL.
 * `TextureManager.addRenderTexture` is a new method that will add a Render Texture into the Texture Manager, allowing you to use it as the texture for Game Objects just by using the texture key. Modifying the source Render Texture will immediately modify any Game Objects using it.
 * TextureSource has a new boolean property `isRenderTexture` which is set automatically when it's created.
+* The Canvas Renderer has a new method `setContext` which allows it to swap the context being drawn to by all draw operations. Call the method with no arguments to reset it to the default game canvas.
