         * @param {string} urlArg- This contains one of the following:
         *                         1. A conventional http URL, e.g. 'http://...' or 'file://...'
         *                         2. A base64 string of in-line texture data, e.g. 'data:image/jpg;base64,/...'
         *                         3. An indicator that data being passed using the buffer parameter, e.g. 'data:mytexture.jpg'
         *
         * @param {boolean} noMipmap- When true, no mipmaps shall be generated.  Ignored for compressed textures.  They must be in the file.
         * @param {boolean} invertY- When true, image is flipped when loaded.  You probably want true. Ignored for compressed textures.  Must be flipped in the file.
         * @param {Scene} scene- Needed for loading to the correct scene.
         * @param {number} samplingMode- Mode with should be used sample / access the texture.  Default: TRILINEAR
         * @param {callback} onLoad- Optional callback to be called upon successful completion.
         * @param {callback} onError- Optional callback to be called upon failure.
         * @param {ArrayBuffer | HTMLImageElement} buffer- A source of a file previously fetched as either an ArrayBuffer (compressed or image format) or HTMLImageElement (image format)
         * @param {WebGLTexture} fallback- An internal argument in case the function must be called again, due to etc1 not having alpha capabilities.
         * @param {number} format-  Internal format.  Default: RGB when extension is '.jpg' else RGBA.  Ignored for compressed textures.
         *
         * @returns {WebGLTexture} for assignment back into BABYLON.Texture

         * The parameter `subdivisions` sets the number of subdivisions (postive integer, default 4). The more subdivisions, the more faces on the icosphere whatever its size.
         * The parameter `flat` (boolean, default true) gives each side its own normals. Set it to false to get a smooth continuous light reflection on the surface.
         * You can also set the mesh side orientation with the values : BABYLON.Mesh.FRONTSIDE (default), BABYLON.Mesh.BACKSIDE or BABYLON.Mesh.DOUBLESIDE
         * Detail here : http://doc.babylonjs.com/tutorials/02._Discover_Basic_Elements#side-orientation

         * Creates a ribbon mesh.
         * The ribbon is a parametric shape :  http://doc.babylonjs.com/tutorials/Parametric_Shapes.  It has no predefined shape. Its final shape will depend on the input parameters.
         *
         * Please read this full tutorial to understand how to design a ribbon : http://doc.babylonjs.com/tutorials/Ribbon_Tutorial
         * The parameter `pathArray` is a required array of paths, what are each an array of successive Vector3. The pathArray parameter depicts the ribbon geometry.
         * The parameter `closeArray` (boolean, default false) creates a seam between the first and the last paths of the path array.
         * The parameter `closePath` (boolean, default false) creates a seam between the first and the last points of each path of the path array.
         * The parameter `offset` (positive integer, default : rounded half size of the pathArray length), is taken in account only if the `pathArray` is containing a single path.
         * It's the offset to join the points from the same path. Ex : offset = 10 means the point 1 is joined to the point 11.
         * The optional parameter `instance` is an instance of an existing Ribbon object to be updated with the passed `pathArray` parameter : http://doc.babylonjs.com/tutorials/How_to_dynamically_morph_a_mesh#ribbon
         * You can also set the mesh side orientation with the values : BABYLON.Mesh.FRONTSIDE (default), BABYLON.Mesh.BACKSIDE or BABYLON.Mesh.DOUBLESIDE
         * If you create a double-sided mesh, you can choose what parts of the texture image to crop and stick respectively on the front and the back sides with the parameters `frontUVs` and `backUVs` (Vector4).
         * Detail here : http://doc.babylonjs.com/tutorials/02._Discover_Basic_Elements#side-orientation
         * The optional parameter `invertUV` (boolean, default false) swaps in the geometry the U and V coordinates to apply a texture.
         * The parameter `uvs` is an optional flat array of `Vector2` to update/set each ribbon vertex with its own custom UV values instead of the computed ones.
         * The parameters `colors` is an optional flat array of `Color4` to set/update each ribbon vertex with its own custom color values.
         * Note that if you use the parameters `uvs` or `colors`, the passed arrays must be populated with the right number of elements, it is to say the number of ribbon vertices. Remember that
         * if you set `closePath` to `true`, there's one extra vertex per path in the geometry.
         * Moreover, you can use the parameter `color` with `instance` (to update the ribbon), only if you previously used it at creation time.
         * The mesh can be set to updatable with the boolean parameter `updatable` (default false) if its internal geometry is supposed to change once created.

         * The parameters `diameterTop` and `diameterBottom` overwrite the parameter `diameter` and set respectively the top cap and bottom cap diameter (floats, default 1). The parameter "diameterBottom" can't be zero.
         * The parameter `tessellation` sets the number of cylinder sides (positive integer, default 24). Set it to 3 to get a prism for instance.
         * The parameter `subdivisions` sets the number of rings along the cylinder height (positive integer, default 1).
         * The parameter `hasRings` (boolean, default false) makes the subdivisions independent from each other, so they become different faces.
         * The parameter `enclose`  (boolean, default false) adds two extra faces per subdivision to a sliced cylinder to close it around its height axis.
         * The parameter `arc` (float, default 1) is the ratio (max 1) to apply to the circumference to slice the cylinder.
         * You can set different colors and different images to each box side by using the parameters `faceColors` (an array of n Color3 elements) and `faceUV` (an array of n Vector4 elements).
         * The value of n is the number of cylinder faces. If the cylinder has only 1 subdivisions, n equals : top face + cylinder surface + bottom face = 3
         * Now, if the cylinder has 5 independent subdivisions (hasRings = true), n equals : top face + 5 stripe surfaces + bottom face = 2 + 5 = 7
         * Finally, if the cylinder has 5 independent subdivisions and is enclose, n equals : top face + 5 x (stripe surface + 2 closing faces) + bottom face = 2 + 5 * 3 = 17
         * Each array (color or UVs) is always ordered the same way : the first element is the bottom cap, the last element is the top cap. The other elements are each a ring surface.
         * If `enclose` is false, a ring surface is one element.
         * If `enclose` is true, a ring surface is 3 successive elements in the array : the tubular surface, then the two closing faces.

         *
         * tuto : http://doc.babylonjs.com/tutorials/Mesh_CreateXXX_Methods_With_Options_Parameter#polyhedron
         * The parameter `type` (positive integer, max 14, default 0) sets the polyhedron type to build among the 15 embbeded types. Please refer to the type sheet in the tutorial
         *  to choose the wanted type.
         * The parameter `size` (positive float, default 1) sets the polygon size.
         * You can overwrite the `size` on each dimension bu using the parameters `sizeX`, `sizeY` or `sizeZ` (positive floats, default to `size` value).
         * You can build other polyhedron types than the 15 embbeded ones by setting the parameter `custom` (`polyhedronObject`, default null). If you set the parameter `custom`, this overwrittes the parameter `type`.
         * A `polyhedronObject` is a formatted javascript object. You'll find a full file with pre-set polyhedra here : https://github.com/BabylonJS/Extensions/tree/master/Polyhedron
         * You can set the color and the UV of each side of the polyhedron with the parameters `faceColors` (Color4, default `(1, 1, 1, 1)`) and faceUV (Vector4, default `(0, 0, 1, 1)`).
         * To understand how to set `faceUV` or `faceColors`, please read this by considering the right number of faces of your polyhedron, instead of only 6 for the box : http://doc.babylonjs.com/tutorials/CreateBox_Per_Face_Textures_And_Colors
         * The parameter `flat` (boolean, default true). If set to false, it gives the polyhedron a single global face, so less vertices and shared normals. In this case, `faceColors` and `faceUV` are ignored.
         * You can also set the mesh side orientation with the values : BABYLON.Mesh.FRONTSIDE (default), BABYLON.Mesh.BACKSIDE or BABYLON.Mesh.DOUBLESIDE
         * If you create a double-sided mesh, you can choose what parts of the texture image to crop and stick respectively on the front and the back sides with the parameters `frontUVs` and `backUVs` (Vector4).
         * Detail here : http://doc.babylonjs.com/tutorials/02._Discover_Basic_Elements#side-orientation
         * The mesh can be set to updatable with the boolean parameter `updatable` (default false) if its internal geometry is supposed to change once created.

         * A decal is a mesh usually applied as a model onto the surface of another mesh. So don't forget the parameter `sourceMesh` depicting the decal.
         * The parameter `position` (Vector3, default `(0, 0, 0)`) sets the position of the decal in World coordinates.
         * The parameter `normal` (Vector3, default `Vector3.Up`) sets the normal of the mesh where the decal is applied onto in World coordinates.
         * The parameter `size` (Vector3, default `(1, 1, 1)`) sets the decal scaling.
         * The parameter `angle` (float in radian, default 0) sets the angle to rotate the decal.

            Mapping Texture Coordinates to Cube Map Faces
            Because there are multiple faces, the mapping of texture coordinates to positions on cube map faces
            is more complicated than the other texturing targets.  The EXT_texture_cube_map extension is purposefully
            designed to be consistent with DirectX 7's cube map arrangement.  This is also consistent with the cube
            map arrangement in Pixar's RenderMan package.
            For cube map texturing, the (s,t,r) texture coordinates are treated as a direction vector (rx,ry,rz)
            emanating from the center of a cube.  (The q coordinate can be ignored since it merely scales the vector
            without affecting the direction.) At texture application time, the interpolated per-fragment (s,t,r)
            selects one of the cube map face's 2D mipmap sets based on the largest magnitude coordinate direction
            the major axis direction). The target column in the table below explains how the major axis direction
            maps to the 2D image of a particular cube map target.
    
            major axis
            direction     target                              sc     tc    ma
            ----------    ---------------------------------   ---    ---   ---
            +rx          GL_TEXTURE_CUBE_MAP_POSITIVE_X_EXT   -rz    -ry   rx
            -rx          GL_TEXTURE_CUBE_MAP_NEGATIVE_X_EXT   +rz    -ry   rx
            +ry          GL_TEXTURE_CUBE_MAP_POSITIVE_Y_EXT   +rx    +rz   ry
            -ry          GL_TEXTURE_CUBE_MAP_NEGATIVE_Y_EXT   +rx    -rz   ry
            +rz          GL_TEXTURE_CUBE_MAP_POSITIVE_Z_EXT   +rx    -ry   rz
            -rz          GL_TEXTURE_CUBE_MAP_NEGATIVE_Z_EXT   -rx    -ry   rz
    
            Using the sc, tc, and ma determined by the major axis direction as specified in the table above,
            an updated (s,t) is calculated as follows
            s   =   ( sc/|ma| + 1 ) / 2
            t   =   ( tc/|ma| + 1 ) / 2
            If |ma| is zero or very nearly zero, the results of the above two equations need not be defined
            (though the result may not lead to GL interruption or termination).  Once the cube map face's 2D mipmap
            set and (s,t) is determined, texture fetching and filtering proceeds like standard OpenGL 2D texturing.
