/************************************************************************
* Screen buffer structure represents the win32 screen buffer object. *
* Internally, the portion of the buffer being shown CAN loop past the *
* bottom of the virtual buffer and wrap around to the top. Win32 does *
* not do this. I decided to do this because it eliminates the need to *
* do a massive memcpy() to scroll the contents of the buffer up to *
* scroll the screen on output, instead I just shift down the position *
* to be displayed, and let it wrap around to the top again. *
* The VirtualX member keeps track of the top X coord that win32 *
* clients THINK is currently being displayed, because they think that *
* when the display reaches the bottom of the buffer and another line *
* being printed causes another line to scroll down, that the buffer IS *
* memcpy()'s up, and the bottom of the buffer is still displayed, but *
* internally, I just wrap back to the top of the buffer. *
