[Public WebGL] Depth Texture Extension

Hi folks,

I brought the contradiction between OES_depth_texture and OES_packed_depth_stencil with respect to support for cube-depth textures to the attention of the ES Working Group.  In a survey of the vendors which implement the OES_depth_texture extension it turns out that some of them support depth cube maps and others do not.  As such, we have updated the specification for OES_depth_texture so that it only provides support for 2D depth textures.  In the future, the depth cube map functionality will be advertised under a separate extension (not yet published). 

The OES_depth_texture specification (at http://www.khronos.org/registry/gles/extensions/OES/OES_depth_texture.txt) has been updated to reflect these changes.

As such, the WEBGL_depth_texture proposal can be changed back to OES_depth_texture.

Hope this helps,
