+ * $Log: ugldrawpix.c,v $
+ * Revision 1.1  2001/08/20 16:07:11  brianp
+ * WindML driver (Stephane Raimbault)
+ *
+ * Revision 1.5  2000/12/24 22:53:54  pesco
+ * * demos/Makefile.am (INCLUDES): Added -I$(top_srcdir)/util.
+ * * demos/Makefile.X11, demos/Makefile.BeOS-R4, demos/Makefile.cygnus:
+ * Essentially the same.
+ * Program files updated to include "readtex.c", not "../util/readtex.c".
+ * * demos/reflect.c: Likewise for "showbuffer.c".
+ *
+ *
+ * * Makefile.am (EXTRA_DIST): Added top-level regular files.
+ *
+ * * include/GL/Makefile.am (INC_X11): Added glxext.h.
+ *
+ *
+ * * src/GGI/include/ggi/mesa/Makefile.am (EXTRA_HEADERS): Include
+ * Mesa GGI headers in dist even if HAVE_GGI is not given.
+ *
+ * * configure.in: Look for GLUT and demo source dirs in $srcdir.
+ *
+ * * src/swrast/Makefile.am (libMesaSwrast_la_SOURCES): Set to *.[ch].
+ * More source list updates in various Makefile.am's.
+ *
+ * * Makefile.am (dist-hook): Remove CVS directory from distribution.
+ * (DIST_SUBDIRS): List all possible subdirs here.
+ * (SUBDIRS): Only list subdirs selected for build again.
+ * The above two applied to all subdir Makefile.am's also.
+ *
+ * Revision 1.4  2000/09/08 21:45:21  brianp
+ * added dither key option
+ *
+ * Revision 1.3  1999/10/28 18:23:29  brianp
+ * minor changes to Usage() function
+ *
+ * Revision 1.2  1999/10/21 22:13:58  brianp
+ * added f key to toggle front/back drawing
+ *
+ * Revision 1.1.1.1  1999/08/19 00:55:40  jtg
+ * Imported sources
+ *
+ * Revision 3.3  1999/03/28 18:18:33  brianp
+ * minor clean-up
+ *
+ * Revision 3.2  1998/11/05 04:34:04  brianp
+ * moved image files to ../images/ directory
+ *
+ * Revision 3.1  1998/02/22 16:43:17  brianp
+ * added a few casts to silence compiler warnings
+ *
+ * Revision 3.0  1998/02/14 18:42:29  brianp

+ * WindML driver (Stephane Raimbault)
+ *
+ * Revision 1.5  2001/03/27 17:35:26  brianp
+ * set initial window pos
+ *
+ * Revision 1.4  2000/12/24 22:53:54  pesco
+ * * demos/Makefile.am (INCLUDES): Added -I$(top_srcdir)/util.
+ * * demos/Makefile.X11, demos/Makefile.BeOS-R4, demos/Makefile.cygnus:
+ * Essentially the same.
+ * Program files updated to include "readtex.c", not "../util/readtex.c".
+ * * demos/reflect.c: Likewise for "showbuffer.c".
+ *
+ *
+ * * Makefile.am (EXTRA_DIST): Added top-level regular files.
+ *
+ * * include/GL/Makefile.am (INC_X11): Added glxext.h.
+ *
+ *
+ * * src/GGI/include/ggi/mesa/Makefile.am (EXTRA_HEADERS): Include
+ * Mesa GGI headers in dist even if HAVE_GGI is not given.
+ *
+ * * configure.in: Look for GLUT and demo source dirs in $srcdir.
+ *
+ * * src/swrast/Makefile.am (libMesaSwrast_la_SOURCES): Set to *.[ch].
+ * More source list updates in various Makefile.am's.
+ *
+ * * Makefile.am (dist-hook): Remove CVS directory from distribution.
+ * (DIST_SUBDIRS): List all possible subdirs here.
+ * (SUBDIRS): Only list subdirs selected for build again.
+ * The above two applied to all subdir Makefile.am's also.
+ *
+ * Revision 1.3  2000/09/29 23:09:39  brianp
