+ * $Log: ugltexcyl.c,v $
+ * Revision 1.2 2001/09/10 19:21:13 brianp
+ * WindML updates (Stephane Raimbault)
+ *
+ * Revision 1.1 2001/08/20 16:07:11 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
+ * added fps output
+ *
+ * Revision 1.2 1999/10/21 16:39:06 brianp
