* ParametricGeometry: Correct Format

This will unset the current rendertarget of the renderer if no
rendertarget is specified to the render()-call.

They didn't produce correct eye translations in all cases (specifically
standing scenes.) This reverted version may not be 100% accurate on
future hardware (if the eyes have a rotation component, for example) but
it's correct on all current WebVR implementations. That's better than
blatantly wrong in some cases.

Use of the WebVR-provided projection matricies has been left in, since
that was working correctly.

* BufferSubdivisionModifier: cleanup

* BufferSubdivisionModifier: More cleanup

The spec has been updated so that `requestPresent` can accept empty arrays for `leftBounds` and `rightBounds`. Though Chromium returns `null` for these properties by default, Firefox returns empty arrays, and there is a proposal to make those non-nullable. This patch should fix rendering for Firefox, which is currently broken.

issue #9739

- Move computation from fragment shader to vertex shader wherever possible
- Eliminate some dead shader code and comments
- Fix spelling of "Rayleigh"

* dynamic uniforms are no longer

* Add Object3d callback docs

* tighten language a bit

* Add Light Pre-Pass Support to WebGLDeferredRenderer

* Remove lightPrePass parameter from WebGLDeferredRenderer constructor

* Add attributes to EditorControls

Add attributes to EditorControls to be able to change speed of controls

* Changed attribute name factor to speed

* TubeBufferGeometry: Initial Commit

* TubeBufferGeometry: Cleanup

* webgl_geometry_extrude_splines: cleanup

* TubeBufferGeometry: Changed FrenetFrames to private function

* TubeBufferGeometry: Changed FrenetFrames function call

- Thanks @Mugen87!

Eval was being used to construct a regex pattern. This replaces that with the RegExp constructor.

* Moved FrenetFrames calculation from TubeBufferGeometry to Curve

* Curve: Clean up

* ExtrudeGeometry: Removed reference to TubeGeometry

When using a mouse wheel to zoom in and out quickly, sometimes zoomCamera's factor can go negative. When that happens, _zoomStart.y never gets reset to 0, causing zooming to stop. The fix is to always update _zoomStart, but only update _eye when (factor != 1.0 && zoom > 0.0) .

That is how it should look like according to rollup plugin conventions: https://github.com/rollup/rollup/wiki/Plugins
