A patch to introduce this extension has been accepted by Mozilla to
mozilla-inbound: https://bugzilla.mozilla.org/show_bug.cgi?id=728354

- The extension name MOZ_EXT_texture_filter_anisotropic is used by firefox.
- A conformance test has been added for this feature:
- Is it possible to accept this conformance test upstream to the Khronos
conformance test suite?
- A demo for anisotropic filtering is available at:
- Sample picture of the demo: http://codeflow.org/pictures/anisotropy.jpg

Example Code:

var ext = gl.getExtension('MOZ_EXT_texture_filter_anisotropic');
    var max = gl.getParameter(ext.MAX_TEXTURE_MAX_ANISOTROPY);
    gl.texParameterf(target, ext.TEXTURE_MAX_ANISOTROPY, max);

Angle OpenGL works fine, but Direct3D support is not yet there for this
feature, requirement described there:
