MD2Character is an object encapsulating character body, multiple weapons and multiple skins as a single entity.

Default computation of morph normals for all models with morphs was taking unnecessary time and memory.

Also made it less resource intensive to recompute morph normals.

It seems to work, though not sure yet how to handle some things. Also for the moment it's implemented just for Lambert material.

As per discussion in #1207

Made shadow transparent (albeit doesn't go well with canvas_geometry_earth :/). Updated webgl_multiple_views example for the new IcosahedronGeometry.

Seemed like a few people around the net were looking for one

Some broken stuff... :/

Keeping the old IcosahadrenGeometry and OctahedronGeometry to double check results later.

This is for easier visual checking of RGBA encoded depth maps.

Before SpotLight was a weird mix of shadow casted from PointLight and light casted from DirectionalLight.

As per discussion here: https://github.com/alteredq/three.js/commit/835b57addaf328412b61a2b644ff5efd7fe6d25e

Bah, this one was tricky. World positions are not updated for objects that are not part of the scene graph so spotlight target was just hanging in limbo.

Thanks GUI-DAT ;)

Sidenote: these extra verbose Closure warnings are starting to pay off - I keep catching subtle bugs (like missing dependencies in rarely used code corners).

This allows to have different shadow map parameters for different lights, also it's easier to access parameters for tweaking / debugging.

Changes:

renderer.shadowMapWidth    => spotLight.shadowMapWidth
renderer.shadowMapHeight   => spotLight.shadowMapHeight

renderer.shadowMapBias     => spotLight.shadowBias
renderer.shadowMapDarkness => spotLight.shadowDarkness

renderer.shadowCameraNear  => spotLight.shadowCameraNear
renderer.shadowCameraFar   => spotLight.shadowCameraFar
renderer.shadowCameraFov   => spotLight.shadowCameraFov

Also added new uniform type "v2v" for array of Vector2 (to support per-light sizes of shadow maps).

This is for seeing how camera actually looks (frustum, line-of-sight, up), it's not a camera. Not sure about the name.

Shadows should be now done more correctly and also be a bit less fussy. Before RGBA encoded depth maps were getting messed up with blending (that's why everything was extremely sensitive to frustum size).

All examples with shadows had to be re-tweaked (shadows now behave differently).

This is necessary for OpenGL where pow(0,0) is undefined and apparently can be negative, leading to negative specular light (in DirectX you just get zero).

Made by hand, trying to give more shininess to nose, forehead and lips, less to everything else.
