-/** Assigns a non-rectangular shape to the window.
- This function gives an arbitrary shape (not just a rectangular region) to an Fl_Window.
- An Fl_Image of any dimension can be used as mask; it is rescaled to the window's dimension as needed.
- 
- The layout and widgets inside are unaware of the mask shape, and most will act as though the window's
- rectangular bounding box is available
- to them. It is up to you to make sure they adhere to the bounds of their masking shape.
- 
- The \p img argument can be an Fl_Bitmap, Fl_Pixmap, Fl_RGB_Image or Fl_Shared_Image:
- \li With Fl_Bitmap or Fl_Pixmap, the shaped window covers the image part where bitmap bits equal one,
- or where the pixmap is not fully transparent.
- \li With an Fl_RGB_Image with an alpha channel (depths 2 or 4), the shaped window covers the image part
- that is not fully transparent.
- \li With an Fl_RGB_Image of depth 1 (gray-scale) or 3 (RGB), the shaped window covers the non-black image part.
- \li With an Fl_Shared_Image, the shape is determined by rules above applied to the underlying image.
- The shared image should not have been scaled through Fl_Shared_Image::scale().
- 
- Platform details:
- \li On the unix/linux platform, the SHAPE extension of the X server is required.
- This function does control the shape of Fl_Gl_Window instances.
- \li On the MSWindows platform, this function does nothing with class Fl_Gl_Window.
- \li On the Mac platform, OS version 10.4 or above is required. 
- An 8-bit shape-mask is used when \p img is an Fl_RGB_Image:
- with depths 2 or 4, the image alpha channel becomes the shape mask such that areas with alpha = 0
- are out of the shaped window;
- with depths 1 or 3, white and black are in and out of the
- shaped window, respectively, and other colors give intermediate masking scores.
- This function does nothing with class Fl_Gl_Window.
-
- The window borders and caption created by the window system are turned off by default. They
- can be re-enabled by calling Fl_Window::border(1).
- 
- A usage example is found at example/shapedwindow.cxx.

- \version 1.3.3 (and requires compilation with FL_ABI_VERSION >= 10303)
