New member function Fl_Image::scale(int width, int height) to set the FLTK size of an image.

Each image has now two sizes implemented as follows:
   - the pixel size is stored in private members pixel_w_ and pixel_h_
    with public accessors pixel_w() and pixel_h()
   - the FLTK size is stored in private members w_ and h_ and read by w() and h()
   - when the image is constructed, the two sizes have the same value
   - the protected w(int) and h(int) member functions set both FLTK and pixel sizes.
   - the public scale(int, int) member function is essentially nothing but
   set the FLTK size and don't change the pixel size.
   - when the image is drawn, its FLTK size determines how big it is drawn, its pixel
   size determines how much data are available to draw it.

FLTK 1.3.4 with FL_ABI_VERSION=10304 contained an equivalent member function
but only for the Fl_Shared_Image class.
