From #1454, small edit to TrackballControls.js to zoom properly with an OrthographicCamera
Created a `TrackballControls` for `OrthographicCamera`
Removed `checkDistances` and associated variables
Create webgl_video_panorama_equirectangular.html

Hello,
here is an example forked from webgl_panorama_equirectangular.html to map video texture instead of a still video. Just add a textures/pano.webm equirectangular video file. I tested it with some material I have, I need to clear the possible copyright issues with the author, let me know if you are interested.
Thank you for your work,
Cheers,

vertexColors should default to 'THREE.NoColors' not 'false' - Fixes #2180
Cleaned up example.
OrbitControls update condition should check offset and orientation

`OrbitControls` only checks the camera position offset to decide when to
emit a `change` event. When the camera is near either pole and the user
is rotating in azimuth, the position changes very little while the
camera orientation changes a lot. As a result, the view feels 'stuck' in
azimuth near the poles.

This patch modifies the camera update condition to take into account
both the change in offset and orientation between `change` events. The
update condition is now:

    (camera displacement)^2 + (camera rotation in radians)^2 > EPS

The additional term is computed from the dot product of the camera's
orientation quaternion at consecutive time steps:

    8 * (1 - q.r)

The second-order Taylor expansion of this expression is the square of
the camera rotation angle between frames.
