* support custom clear colors in ManuallMSASRenderPass like RenderPass supports.

* fix bugs in clearColor/clearAlpha for MSAA.

* cleanup.

* simplify clearColor in ManualMSAARenderPAss + RenderPass.

* WestLAngley suggestion.

* use only one composer, rather than two.  Just turn on and off passes.  Allow for toggling autoRotate

* avoid allocating THREE.Color classes when possible.

* fixed.

* simplify code via automatic hoisting.

* hex rather than color.

* Fix Sky Shader on Android/S6 (#8382)

`exp(n)` does not return the correct value, so I replaced it with `pow(e, n)`.

* Editor: Include VRControls/VREffect when needed.

* Editor: Workaround for Storage not being ready in time.

* Editor: Fixed edit button.

* Added comment explaining change in shader function #8382, #8614

- Added texture minifier and magnifier filters to variables.
 - Added missing null dependencies check in compute()
 - Two simple loop optimizations (store count in a variable)
 - Water demo: Improved noise appearance by raising noise z parameter.
 - Code formatting (indentation) and clean up.

ShaderChunk: Moved normal_flip out of envmap_fragment and normal_fragment. See fc1159a6.

This implementation of projectOnVector is faster and shorter than the current version, and it requires no intermediate Vector3 allocation

* Let THREE.PropertyBinding.parseTrackName() follow code style

* Let CleanupPropertyBinding follow code style more
