* Don't treat render targets like textures.

Expect Texture instances from now on. Added backwards compatibility
measures to ensure that render targets can still act as textures for the
time being. A deprecation warning will be given. Resolves #8615.

* Added comments to clear up RT-Cube detection.

* Revised the previously added comments.

* Added a TODO note.

Forgot to include this one in the last commit.

* Documentation: updated WebGLRenderTarget.

* Docs: added more Texture info to WebGLRenderTarget.

Also removed an unnecessary html line break.

* Docs: added a notification to ShaderMaterial.

WebGLRenderTarget and WebGLRenderTargetCube must not be used as
uniforms. Their texture instance must be used instead.

* Docs: revised a notification in ShaderMaterial.

- See #8749

* Removed useless and outdated ShadowMapPlugin docs.

* Consistified WebGLState, added culling.

* Let WebGLShadowMap set culling through WebGLState.

* WebGLShadowMap: Removed redundant state setup.

* WebGLRenderer: Removed needless factorization.

* Removed cull state mess from WebGLShadowMap.

- Instead flip .side on the depth material with the same effect.
- See #8760.

* Updated builds.

meshphongmaterial normalMapScale -> normalScale

* no more limitation on dragging area
* drag cubes // to camera front/back planes

* Remove arguments to allow optimalisations

* Change constructor based on @mrdoob's argument

* Fix issue with renaming of argument

* convert space to tabs

* cleanup docs

* don't forget the linefeed in docs

* docs cleanup

* Update Color.html

It became unnessecary.

* Fix VREffect support for webvr-polyfill (#8712)
- correctly set `isPresenting` in full screen mode
- webvr-polyfill fires fullscreenchange in VR mode
- fix needed for setting main window to full screen while presenting

* Code clean-up (#8748, #8712)
- Added parentheses to clarify per @mrdoob
- More spaces
- cast `isPresenting` to boolean

* Check if vrHMD is undefined (#8748, #8712)

* Improved precision of RGBA fixpoint packing.

* Added switch to enable double-sided shadow casters.

- Off by default, see #8692

* Updated WebGLRenderer docs, shadow mapping.

* Enabled back face shadows, webgl_clipping_advanced.

* default value for constructor autostart

* document default values for optional parameters

* Revert "document default values for optional parameters"

This reverts commit f1d33aa28401658e3622852755a1b5cb7b0e15c6.

* document defaults for raycaster methods

* Removed leftover inclusion of AnimationClipCreator.

- See #8677
  https://github.com/mrdoob/three.js/issues/8677#issuecomment-213629279

* Clarified AnimationMixer loop mode handling.

- See #8719

* remove usage of parameters in setFromMatrixColumn

* This fixes the usage of setFromMatrixColumn

No vertex and no index for cap with 0 radius

See #8685

The indexCount was rigth but the vertexCount was wrong. The squares on
each plane (face) have common vertices
