* Added a "constant wave" in the pattern node * Updated graphEdit to detect and forbid loops * Modified code that renders to texture to update a texture instead of returning one (so we avoid updating everything and rely on everything being updated automatically wrt textures) * base library is loaded from filesystem (instead of package) if available
