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