Added deprecated messages to more critical changes.
Updated builds.
SoftwareRenderer now features zbuffering. @rygorous ftw!
SoftwareRenderer: Small fixes.
Update docs/api/materials/MeshBasicMaterial.html

Change the docs to reflect the true default of the fog parameter in MeshBasicMaterial.
SoftwareRenderer: Removed unneded call and added compatibility methods for WebGLRenderer (uh...).
Projector: Culling vertices on the x and y axis too.
However, this can create glitches on extreme cases when the polygon is inside the frustum but the vertices are not.
Maybe this can be achieved with Box3 in a performant way?
