Class description
Objects of this tuple class can be passed as the indexes slot of a non-instanced render-set to instruct render to assemble primitives from the active vertex-array by using multiple arrays of indexes in CPU or GPU memory.
The buffer slot contains either a buffer object to read indexes from, or f to read from CPU memory.
The ptrs slot contains either a void*-array of pointers to the starts of index data, or a pointer-sized ulong-array of offsets into buffer.
The counts slot contains a uint-array containing the number of indexes to read from each pointer or offset in ptrs.
The index-type slot contains an index-type value specifying whether the arrays consist of ubyte-indexes, ushort-indexes, or uint-indexes.
