[x3d-public] MatrixTextureTransform node

[Andreas Plesch]

x3dom introduced a MatrixTextureTransform node in the Texturing
component, mostly to support glTF to x3d translation since gltf allows
for such a texture coordinate transform matrix. It accepts a 2x2
matrix which is the equivalent of the transformation matrix resulting
from the scale and rotation of a regular TextureTransform node.

Such a node is more convenient than decomposing a provided matrix to
use in a regular TransformMatrix node, only to then recalculate the
matrix from the components when the actual texture coordinates are
computed.

glTF support will make this node very desirable but I am not sure if
other browser have something similar already.
