// New RFB(VNC) gui implementation using the LibVNCServer library to support
// higher resolutions and > 8 bpp graphics modes. This code is based on a patch
// sent by "HH LL" <superminililg@gmail.com>.
// To let mouse work properly in VNC client, you should use USB tablet
// emulation as the input source in bochsrc:
// usb_uhci: enabled=1, port1=tablet
// BTW, Thanks libvncserver, you also can use noVNC client(HTML5 VNC client) to
// view the screen in web browser.
// TODO:
// fix random segfaults in dimension_update()
// fix Windows (MinGW) support
// fix cursor shape after dimension update()
// Define BX_PLUGGABLE in files that can be compiled into plugins. For
// platforms that require a special tag on exported symbols, BX_PLUGGABLE
// is used to know when we are exporting symbols and when we are importing.
