// The paste buffer does NOT exist in the hardware. It is a bochs
// construction that allows the user to "paste" arbitrary length sequences of
// keystrokes into the emulated machine. Since the hardware buffer is only
// 16 bytes, a very small amount of data can be added to the hardware buffer
// at a time. The paste buffer keeps track of the bytes that have not yet
// been pasted.
//
// Lifetime of a paste buffer: The paste data comes from the system
// clipboard, which must be accessed using platform independent code in the
// gui. Because every gui has its own way of managing the clipboard memory
// (in X windows, you're supposed to call Xfree for example), in the platform
// specific code we make a copy of the clipboard buffer with
// "new Bit8u[length]". Then the pointer is passed into
// bx_keyb_c::paste_bytes, along with the length. The gui code never touches
// the pastebuf again, and does not free it. The keyboard code is
// responsible for deallocating the paste buffer using delete [] buf. The
// paste buffer is binary data, and it is probably NOT null terminated.
//
// Summary: A paste buffer is allocated (new) in the platform-specific gui
// code, passed to the keyboard model, and is freed (delete[]) when it is no
// longer needed.
