// Fluid_Image.H

// This class stores the image labels for widgets in fluid.  This is
// not a class in fltk itself, and this will produce different types of
// code depending on what the image type is.  There are private subclasses
// in Fluid_Image.C for each type of image format.  Right now only xpm
// files are supported.
