-/**
- *  \brief Provide a callback that decides if a window region has special properties.
- *
- *  Normally windows are dragged and resized by decorations provided by the
- *  system window manager (a title bar, borders, etc), but for some apps, it
- *  makes sense to drag them from somewhere else inside the window itself; for
- *  example, one might have a borderless window that wants to be draggable
- *  from any part, or simulate its own title bar, etc.
- *
- *  This function lets the app provide a callback that designates pieces of
- *  a given window as special. This callback is run during event processing
- *  if we need to tell the OS to treat a region of the window specially; the
- *  use of this callback is known as "hit testing."
- *
- *  Mouse input may not be delivered to your application if it is within
- *  a special area; the OS will often apply that input to moving the window or
- *  resizing the window and not deliver it to the application.
- *
- *  Specifying NULL for a callback disables hit-testing. Hit-testing is
- *  disabled by default.
- *
- *  Platforms that don't support this functionality will return -1
- *  unconditionally, even if you're attempting to disable hit-testing.
- *
- *  Your callback may fire at any time, and its firing does not indicate any
- *  specific behavior (for example, on Windows, this certainly might fire
- *  when the OS is deciding whether to drag your window, but it fires for lots
- *  of other reasons, too, some unrelated to anything you probably care about
- *  _and when the mouse isn't actually at the location it is testing_).
- *  Since this can fire at any time, you should try to keep your callback
- *  efficient, devoid of allocations, etc.
- *
- *  \param window The window to set hit-testing on.
- *  \param callback The callback to call when doing a hit-test.
- *  \param callback_data An app-defined void pointer passed to the callback.
- *  \return 0 on success, -1 on error (including unsupported).
