Since both front and back buffers will - * return the same structure, you need to be able to distinguish - * somewhere what kind of buffer (front/back) was being asked for, so - * that ddx can render to the right place. That's the problem that the - * following code solves. Note: we couldn't embed this in the LookupID* - * functions because the VALIDATE_DRAWABLE_AND_GC macro often circumvents - * those functions by checking a one-element cache. That's why we're - * mucking with VALIDATE_DRAWABLE_AND_GC. - * - * If you put -DNEED_DBE_BUF_BITS into PervasiveDBEDefines, the window - * structure will have two additional bits defined, srcBuffer and - * dstBuffer, and their values will be maintained via the macros - * SET_DBE_DSTBUF and SET_DBE_SRCBUF (below). If you also - * put -DNEED_DBE_BUF_VALIDATE into PervasiveDBEDefines, the function - * DbeValidateBuffer will be called any time the bits change to give you - * a chance to do some setup.
