Note about view port

In Windows, console API has a concept of screen buffer and window. screen buffer has fixed size. Window may move when an user operates scroll bar(s) or resize a console window. Terminal.size gets size of the screen buffer. Terminal.view gets range of the window. Terminal.screen creates new screen buffer.

In POSIX platform, screen buffer and window are always same size. It may be resized when an user resize a terminal window.

+- Screen Buffer-+
|  scrolled text |
| +- Window ---+ | ...seen from here
| |visible text| |
| |C:\>        | |
| +------------+ | ...seen until here
