Bochs/bochs/gui/wx.cc
Volker Ruppert 9189105a0b - prepared support for sending absolute x/y values from the gui to the mouse emulation 
- new gui method set_mouse_mode_absxy() should switch the gui to absolute
    x/y mode
  - new DEV_mouse_motion() argument 'absxy' indicates whether or not the gui
    sends absolute x/y values
  - USB tablet code prepared to use the new feature
  - TODO: implement this feature for each gui (sdl, win32, wx, x, ...)

//
// wxWidgets VGA display for Bochs. wx.cc implements a custom
// wxPanel called a MyPanel, which has methods to display
// text and VGA graphics on the panel. Normally, a MyPanel
// is instantiated within a MyFrame created by wxmain.cc, but
// this is not a requirement.
//
// The separation between wxmain.cc and wx.cc is as follows:
// - wxmain.cc implements a Bochs configuration interface (CI),
// which is the wxWidgets equivalent of textconfig.cc. wxmain creates
// a frame with several menus and a toolbar, and allows the user to
// choose the machine configuration and start the simulation. Note
// that wxmain.cc does NOT include bochs.h. All interactions
// between the CI and the simulator are through the siminterface
// object.
// - wx.cc implements a VGA display screen using wxWidgets. It is
// is the wxWidgets equivalent of x.cc, win32.cc, macos.cc, etc.
// wx.cc includes bochs.h and has access to all Bochs devices.
// The VGA panel accepts only paint, key, and mouse events. As it
// receives events, it builds BxEvents and places them into a
// thread-safe BxEvent queue. The simulation thread periodically
// processes events from the BxEvent queue (bx_wx_gui_c::handle_events)
// and notifies the appropriate emulated I/O device.
//
