+    <p>
+      In OpenGL ES 3.0 it is explicitly allowed to create a compressed 2D texture with uninitialized
+      data by passing <code>null</code> to <code>glCompressedTexImage2D</code>. In WebGL 2.0,
+      however, this is still explicitly disallowed. Users can use <code>texStorage2D</code> with a
+      compressed internal format to allocate zero-initialized compressed textures; these textures
+      are however immutable, and not completely compatible with textures allocated
+      via <code>compressedTexImage2D</code>.
