Mc2pToggle Buffers.b,Buf.b ; 1, 2 or 3, and 0, 1 or 2. Toggle c2p lacing.

Performs row and column interlacing toggles (if applicable) in the c2p system in
a manner that is designed for use with single, double, or triple-buffered
displays, in which you must specify the current frame number (0..Buffers-1).
Normally you should toggle your buffers with something like Buf=1-Buf, or a
slighly more complicated cycling of the current number for triple-buffered
displays. This command effectively does the same as Mc2pToggleSingle,
Mc2pToggleDouble or Mc2pToggleTriple, although you do have more manual control
over frame number (be careful with misuse of it or you might get wierd results).
