* convert to ES modules

* rebuild

* move shaders back into glsl files

* reinstate polyfills

* add files for buffered and non-buffered ConeGeometry based on CylinderGeometry

* build files with cone

* removing unneeded file

* remove unneeded npm script

* remove build files from pr

* decouple PerspectiveCamera parameters in ObjectLoader. see comment: https://github.com/mrdoob/three.js/pull/8561/files/7eea5d47d86a6376175761cddab2742f17de177f#r59205742

* null -> undefined checking of data.view

* only export view if defined.

* Let ObjectLoader load extended PerspectiveCamera.

Part 2 - "Oh complexity, how have I missed you!"

* Let ObjectLoader ignore perspectiveCam.focalLength.

RingGeometry `s BufferGeometry port

LatheGeometry modified to use Vector2 and allowing axe choice by the
called.
The axe is designed by a letter because I didn't know where I should put
a constance definition.
The loop that create the geometry is not optimized for speed => the axis
test is in the inner loop.
Should not break any existing code.
Doc and exemple not updated yet.

LatheGeometry is a standard geometry but it's not processed by
parseGeometries of ObjectLoader.

* Shorter (less typo-prone)
* More intuitive (also "aligns" with gl.POINTS)
* Makes a nice API (Mesh, Line, Points).

issue #7103
ObjectLoader.js, method parseTextures, offset is now restored.
