/************************************************************************
 * 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.               *
