Extremely rough implementation at https://github.com/jdm/servo/tree/teximage3d, which is enough to get http://webglsamples.org/WebGL2Samples/#texture_2d_array and http://webglsamples.org/WebGL2Samples/#texture_3d running. Next steps include:

actually trying to implement the 3d texture/2d texture array validation checks, instead of relying on some hacks in the 2d texture validation
implementing the other webidl entrypoints for TexImageSource
figuring out how to merge the existing tex_image_2d/TexImage2D implementations with the duplicated 3d texture code
running tests
