+//

+// fl_draw_image test program for the Fast Light Tool Kit (FLTK).

+//

+// Be sure to try every visual with the -v switch and try -m (monochrome)

+// on each of them.

+//

+// This program requires either the libjpeg.a library or an internal DD

+// library to read images (this is chosen by the presence of the "DD"

+// #define).

+//

+// To get the jpeg library:

+//

+// The "official" archive site for this software is ftp.uu.net (Internet

+// address 192.48.96.9).  The most recent released version can always be

+// found there in directory graphics/jpeg.  This particular version will

+// be archived as graphics/jpeg/jpegsrc.v6a.tar.gz.

+//

+// The makefile assummes you decompressed and build these in a directory

+// called "jpeg-6a" in the same location as the "FL" directory.
