_s_t_r_i_d_e Specifies the offset in bytes between each aggregate array
element.

ffffggggllllIIIInnnntttteeeerrrrlllleeeeaaaavvvveeeeddddAAAArrrrrrrraaaayyyyssss lets you specify and enable individual color,
normal, texture and vertex arrays whose elements are part of a larger
aggregate array element. For some implementations, this is more
efficient than specifying the arrays separately.
If _s_t_r_i_d_e is 0, the aggregate elements are stored consecutively.
Otherwise, _s_t_r_i_d_e bytes occur between the beginning of one aggregate
array element and the beginning of the next aggregate array element.
_f_o_r_m_a_t serves as a ``key'' describing the extraction of individual arrays
from the aggregate array. If _f_o_r_m_a_t contains a T, then texture
coordinates are extracted from the interleaved array. If C is present,
color values are extracted. If N is present, normal coordinates are
extracted. Vertex coordinates are always extracted.
The digits 2, 3, and 4 denote how many values are extracted. F indicates
that values are extracted as floating-point values. Colors may also be
extracted as 4 unsigned bytes if 4UB follows the C. If a color is
extracted as 4 unsigned bytes, the vertex array element which follows is
located at the first possible floating-point aligned address.

ffffggggllllIIIInnnntttteeeerrrrlllleeeeaaaavvvveeeeddddAAAArrrrrrrraaaayyyyssss is available only if the GL version is 1.1 or
greater.
If ffffggggllllIIIInnnntttteeeerrrrlllleeeeaaaavvvveeeeddddAAAArrrrrrrraaaayyyyssss is called while compiling a display list, it is
not compiled into the list, and it is executed immediately.
Execution of ffffggggllllIIIInnnntttteeeerrrrlllleeeeaaaavvvveeeeddddAAAArrrrrrrraaaayyyyssss is not allowed between the execution of
ffffggggllllBBBBeeeeggggiiiinnnn and the corresponding execution of ffffggggllllEEEEnnnndddd, but an error may or
may not be generated. If no error is generated, the operation is
undefined.
ffffggggllllIIIInnnntttteeeerrrrlllleeeeaaaavvvveeeeddddAAAArrrrrrrraaaayyyyssss is typically implemented on the client side.
Vertex array parameters are client-side state and are therefore not saved
or restored by ffffggggllllPPPPuuuusssshhhhAAAAttttttttrrrriiiibbbb and ffffggggllllPPPPooooppppAAAAttttttttrrrriiiibbbb. Use ffffggggllllPPPPuuuusssshhhhCCCClllliiiieeeennnnttttAAAAttttttttrrrriiiibbbb
