b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * We think that most hardware implementations of DBE will want
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * LookupID*(dbe_back_buffer_id) to return the window structure that the
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * id is a back buffer for. Since both front and back buffers will
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * return the same structure, you need to be able to distinguish
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * somewhere what kind of buffer (front/back) was being asked for, so
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * that ddx can render to the right place. That's the problem that the
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * following code solves. Note: we couldn't embed this in the LookupID*
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * functions because the VALIDATE_DRAWABLE_AND_GC macro often circumvents
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * those functions by checking a one-element cache. That's why we're
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * mucking with VALIDATE_DRAWABLE_AND_GC.
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * If you put -DNEED_DBE_BUF_BITS into PervasiveDBEDefines, the window
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * structure will have two additional bits defined, srcBuffer and
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * dstBuffer, and their values will be maintained via the macros
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * SET_DBE_DSTBUF and SET_DBE_SRCBUF (below). If you also
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * put -DNEED_DBE_BUF_VALIDATE into PervasiveDBEDefines, the function
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * DbeValidateBuffer will be called any time the bits change to give you
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * a chance to do some setup. See the DBE code for more details on this
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * function. We put in these levels of conditionality so that you can do
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * just what you need to do, and no more. If neither of these defines
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * are used, the bits won't be there, and VALIDATE_DRAWABLE_AND_GC will
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * be unchanged. dpw
