Khronos-approved extension specifications are updated in response to
issues and bugs prioritized by the Khronos OpenGL ES Working Group. For
extensions which have been promoted to a core Specification, fixes will
first appear in the latest version of that core Specification, and will
eventually be backported to the extension document. This policy is

OpenGL ES Extension #136

OpenGL ES 2.0 is required.

OES_depth_texture is required. 

This extension is written against the OpenGL ES 2.0 specification

OES_packed_depth_stencil affects the definition of this extension.

This extension extends OES_depth_texture and OES_packed_depth_stencil
to support depth and depth-stencil cube-map textures.

None

Accepted by the <format> parameter of TexImage2D and TexSubImage2D and
<internalFormat> parameter of TexImage2D when <target> is one of the
TEXTURE_CUBE_MAP_* targets:

    DEPTH_COMPONENT          0x1902
    DEPTH_STENCIL_OES        0x84F9
    
Accepted by the <type> parameter of TexImage2D, TexSubImage2D when
<target> is one of the TEXTURE_CUBE_MAP_* targets:

    UNSIGNED_SHORT           0x1403
    UNSIGNED_INT             0x1405
    DEPTH24_STENCIL8_OES     0x88F0

None

Delete the following paragraph which was added by OES_depth_texture:

"Textures with a base internal format of DEPTH_COMPONENT are supported
by texture image specification commands only if <target> is TEXTURE_2D.
Using this format in conjunction with any other <target> will result in
an INVALID_OPERATION error."

Delete the following paragraph which was added by OES_packed_depth_stencil:

"Textures with a base internal format of DEPTH_COMPONENT or DEPTH_STENCIL_OES
are supported by texture image specification commands only if <target> is
TEXTURE_2D.  Using this format in conjunction with any other <target> will
result in an INVALID_OPERATION error."

None

If OES_packed_depth_stencil is not available, any modifications based on 
OES_packed_depth_stencil and any mention of DEPTH_STENCIL_OES
and DEPTH24_STENCIL8_OES are omitted.

Change the error for <targets> accepted by TexImage2D and TexSubImage2D to:

"The error INVALID_OPERATION is generated if <target> is not TEXTURE_2D, or
one of the TEXTURE_CUBE_MAP_* targets."

None.
