		- `running` whether the loop is currently running
		- `deviceWidth`, `deviceHeight` the actual device height (i.e. size * devicePixelRatio). This is needed for glViewport, glScissor, etc.

		### context scaling / viewport

		Before rendering, the 2d context is scaled to the device size (or the scale remains unchanged if `retina` was false). If the context is `"webgl"`, then instead `gl.viewport` will be called with the device size.
		For 2D contexts, `scale()` is called before rendering based on the deviePixelRatio. For WebGL contexts, `gl.viewport()` is called before rendering with the device size.

		If `retina` is false, the device size will be assumed to be the same as the canvas size.
