INT 15 - TopView - SEND MESSAGE - "NEW" - CREATE NEW OBJECT
        AH = 12h
        BH = 01h
        BL = object type to create
            00h (DV 2.0x only) handle is DWORD on top of stack
            01h (DV 2.0x only) use task's window handle
            02h (DV 2.0x only) given task's mailbox (task's handle on stack)
            03h (DV 2.0x only) current task's mailbox
            04h (DV 2.0x only) given task's keyboard (task's handle on stack)
            05h (DV 2.0x only) current task's keyboard object
            08h WINDOW class
            09h MAILBOX class
            0Ah KEYBOARD class
            0Bh TIMER object (counts down 32-bit time in 10ms increments)
            0Fh POINTER object
            10h PANEL object
        STACK: (if window object or WINDOW class)
               DWORD address to jump to (no new task if high word == 0)
               DWORD (reserved) 0 = non-task window, FFFFh = task window
               DWORD bytes for task's private stack (FFFFh == default of 0100h)
               DWORD bytes system memory for input buffer for READ/READN
                        (0 == none, -1 == default--same as logical window size)
               DWORD window size, columns
               DWORD window size, rows
               DWORD length of window title
               DWORD address of window title
Return: DWORD on top of stack is new object handle
Notes:  if a new task is created, it is started with
          AX = BX = SI = DI = BP = 0
          DX:CX = handle of parent task
          DS = ES = SS = segment of private stack (and new task's handle)
        new windows are orphans, inherit the colors/hidden status of the
          creating task's window, and are placed in the upper left hand corner
          of the screen but not automatically redrawn
        new keyboards are closed, and have all object bits cleared except for
          the hardware cursor bit
