/**
 * Creates a plane polygonal mesh.  By default, this is a disc
 * * The parameter `radius` sets the radius size (float) of the polygon (default 0.5)
 * * The parameter `tessellation` sets the number of polygon sides (positive integer, default 64). So a tessellation valued to 3 will build a triangle, to 4 a square, etc
 * * You can create an unclosed polygon with the parameter `arc` (positive float, default 1), valued between 0 and 1, what is the ratio of the circumference : 2 x PI x ratio
 * * 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 : https://doc.babylonjs.com/features/featuresDeepDive/mesh/creation/set#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
 * @param name defines the name of the mesh
 * @param options defines the options used to create the mesh
 * @param scene defines the hosting scene
 * @returns the plane polygonal mesh
 * @see https://doc.babylonjs.com/features/featuresDeepDive/mesh/creation/set#disc-or-regular-polygon
