fltk/test/pixmap_browser.cxx
Michael R Sweet b650366d80 Added XBM, XPM, and PNM image file classes.
The pixmap_browser demo now supports all image formats via Fl_Shared_Image.

Dropped image file stuff from image demo.

Added Fl_Tiled_Image class, which tiles an Fl_Image, useful for tiling a
background image in groups.

Added tiled_image demo.
