Move Fl_Window::shape() from file Fl_Window_Driver.cxx to Fl_Window.cxx

Consequently, the Doxygen documentation of Fl_Window::shape() will reappear.

+ 
+ 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_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 Windows 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.
