  The wxBitmap class encapsulates the concept of a platform-dependent bitmap,
  either monochrome or colour. Platform-specific methods for creating a
  wxBitmap object from an existing file are catered for, and

  You should always use wxICON and wxBITMAP macros because they work for any
  platform (unlike the code above which doesn't deal with wxMac, wxX11, ...) and
  are more short and clear than versions with @c #ifdefs. Even better,
  use the same XPMs on all platforms.
