// -*- ObjC -*-
// Why QDView? Well...
//
// 1) we can trivially obtain a raw pointer to its backing store, so
// 2) no need to putz around with the lockFocus/DataProvider/ImageRep crap; plus
// 3) its buffer's coordinate system is already the right way up for Squeak, so
// 4) we avoid potential recopy (just to have CG recopy again); besides
// 5) QDFlushBuffer is _blindingly_ fast (even compared to drawing directly on
// the framebuffer [go measure it if you don't believe me]); but most importantly
// 6) the QD API is completely free of ObjC and attendant inefficiencies.
