I was trying to implement hatching shader in WebGL and discovered that OES_standard_derivatives extension is not supported yet and functions like dFdx()  or dFdy() can't be used. I was surprised because it is supported by OpenGL ES 2.0. From what I see in the source of http://www.khronos.org/registry/webgl/doc/spec/extensions/ it is one of the planned extensions. Any timeline for supporting it?
