Class description
Objects of this tuple class can be passed as the indexes slot of a render-set to instruct render to assemble primitives from the active vertex-array by using an array of indexes in CPU or GPU memory.
The ptr slot contains a byte-array, alien, or buffer-ptr value referencing the beginning of the index array.
The count slot contains an integer value specifying the number of indexes to supply from the array.
The index-type slot contains an index-type value specifying whether the array consists of ubyte-indexes, ushort-indexes, or uint-indexes.
