Gets the properties of a vertex in the Mesh.
In versions prior to 11.0, color and byte component values were within the range of 0 to 255 instead of 0 to 1.

Synopsis
attributecomponent, ... = Mesh:getVertex( index )
Arguments
number index- The one-based index of the vertex you want to retrieve the information for.
Returns
number attributecomponent- The first component of the first vertex attribute in the specified vertex.
number ...- Additional components of all vertex attributes in the specified vertex.
Notes
The values are returned in the same order as the vertex attributes in the Mesh's vertex format. A standard Mesh that wasn't created with a custom vertex format will return two position numbers, two texture coordinate numbers, and four color components: x, y, u, v, r, g, b, a.
Function
Gets the vertex components of a Mesh that wasn't created with a custom vertex format.
Synopsis
x, y, u, v, r, g, b, a = Mesh:getVertex( index )
Arguments
number index- The index of the vertex you want to retrieve the information for.
Returns
number x- The position of the vertex on the x-axis.
number y- The position of the vertex on the y-axis.
number u- The horizontal component of the texture coordinate.
number v- The vertical component of the texture coordinate.
number r- The red component of the vertex's color.
number g- The green component of the vertex's color.
number b- The blue component of the vertex's color.
number a- The alpha component of the vertex's color.
