+Overview
+
+    This extension exposes the OpenGL ES 3.0 core compressed texture
+    formats in OpenGL ES 2.0.

+    None
+
+New Tokens
+
+    Accepted by the <internalformat> parameter of CompressedTexImage2D and the
+    <format> parameter of CompressedTexSubImage2D:

+
+    Querying COMPRESSED_TEXTURE_FORMATS will include these new formats.
+
+New Procedures and Functions
+
+    None.
+
+Errors
+
+    The error INVALID_VALUE is generated if the <internalformat> parameter of
+    CompressedTexImage2D or the <format> parameter of CompressedTexSubImage2D is
+    COMPRESSED_R11_EAC, COMPRESSED_SIGNED_R11_EAC, COMPRESSED_RGB8_ETC2,
+    COMPRESSED_SRGB8_ETC2, COMPRESSED_RGB8_PUNCHTHROUGH_ALPHA1_ETC2 or
+    COMPRESSED_SRGB8_PUNCHTHROUGH_ALPHA1_ETC2, and imageSize is not
+
+        floor((width + 3) / 4) * floor((height + 3) / 4) * 8
+
+    The error INVALID_VALUE is generated if the <internalformat> parameter of
+    CompressedTexImage2D or the <format> paremeter of CompressedTexSubImage2D is
+    COMPRESSED_RG11_EAC, COMPRESSED_SIGNED_RG11_EAC, COMPRESSED_RGBA8_ETC2_EAC,
+    or COMPRESSED_SRGB8_ALPHA8_ETC2_EAC, and imageSize is not
+
+        floor((width + 3) / 4) * floor((height + 3) / 4) * 16
