        !            11: Subject: New terminal mode for gnuplot.
        !            12: Cc: gregor@kafka.saic.com
        !            13: Status: R
        !            14:
        !            15: Included in this shar is a patch and new files which provide a
        !            16: new terminal type called 'xlib' (for x11-library mode).  The xlib
        !            17: is like the x11 mode modified so that the commands previously
        !            18: sent to the gnuplot_x11 driver are instead put into the output
        !            19: file.  In addition, the gnuplot_x11.c file has been rewritten to
        !            20: be a callable function, which will read a xlib file and draw the
        !            21: described graph in a drawable.
        !            22:
        !            23: The following files are included:
        !            24:
        !            25:        xlib.trm - A copy of x11.trm, modified to use the
        !            26:                normal output file instead of a pipe.
        !            27:
        !            28:        gnulib_x11.c - A rather severe rewrite of gnuplot_x11.c,
        !            29:                as well as a few functions used to interface
        !            30:                into the user code.
        !            31:
        !            32:        gnulib_x11.h - Specs for user callable routines.
        !            33:
        !            34:        xlibtest.c - a test program written in Motif, it will
        !            35:                run gnuplot and build a xlib output file, then
        !            36:                plot that on the screen.  Resizing the window
        !            37:                will redraw the plot, scaled appropriately,
        !            38:                without re-running gnuplot.
        !            39:
        !            40:        xlibtest.demo - the gnuplot command to draw the test plot.
        !            41:
        !            42:        makefile.xlib - minimal make file for the xlibtest program
        !            43:
        !            44: The following patch is included:
        !            45:
        !            46:        term.patch - Patch to 'term.c' which adds the specification
        !            47:                for 'xlib' and includes the 'xlib.trm' file.
        !            48:
        !            49: These changes were made relative to gnuplot3p2b6, and the patch
        !            50: is in unified diff format.  Please drop me a line if you would like
        !            51: it in a different format or relative to a different revision level.
        !            52:
        !            53: To get full use out of the xlib mode, the file gnulib_x11.c needs
        !            54: to be covered by the alternate GPL for libraries, since the gnulib.o
        !            55: file must be linked into the user's executable.  Until that is
        !            56: the case, I will (of course) treat the file as covered by the GPL,
        !            57: meaning that I cannot include the gnulib_x11 drawing routines in my
        !            58: software.
        !            59:
        !            60: The 'xlib' mode provides functionality similar to the 'xpm' terminal
        !            61: mode I sent earlier.  The 'xlib' mode is *much* faster, the disk
        !            62: files are smaller, and plots are re-sizable.  The only advantage
        !            63: of the 'xpm' mode is that XPM format files are more transportable.
        !            64: This would seems to be less important since there is a ppm terminal
        !            65: mode.
        !            66:
        !            67: I'm quite excited about this mode, since it allows executing software
        !            68: the ability to generate gnuplot plots quickly while integrating the
        !            69: output into it's own display.  I hope you will consider it for
        !            70: a future gnuplot release and, at that time, consider the LGPL
        !            71: option.  I would appreciate knowing your views on the subject, since
        !            72: I would like to use the 'xlib' mode in my company's software.
        !            73:
        !            74: Thanks for a great program!
