Return 1 ('event handled') when our view receives an FL_SHOW event.   Does this matter?   It doesn't seem to hurt.

   ?      print help message for hot keys
   ctrl-S toggle stereo left/right eyes
Safer sprintf for subcam report.

Add some redraw() calls to avoid MacOS Lion bug that left cmd box, cmdhist scrollback, and opengl view to go un-refreshed.  Especially when we switch on the timestep row.

Default jpeg quality = 97.

for comparison with -c 'early commands', before window setup.

Add -tilt option to subcam command.

Use glshader.h, and initialize shader stuff (once pre- and again post-window creation).

of main window.  Apparently this used to be necessary to trigger initial redraw,
but (in more recent versions of FLTK?) just causes the main window to become
non-resizable.  Toss it.

Thanks to Jonathan Strawn <jonnyflash@gmail.com>,
UNM ARTS Lab, for figuring this out.

(Why does it need to complain about losing precision on a reinterpret_cast??)

Use Toshiyuki Takahei's FLHACKs.  Reorder functions so we don't
need quite so many of them.  Restructure msg() and warn() likewise.

Set an initial display context number so Gview can track future window changes.

to stop animation.

It now returns void.
Fix (?) interaction between "winsize" and "detach".
At least, it works to say in .partiviewrc
    eval winsize 800x600+400+50
    eval detach hide
to get a bare graphics window with no UI panel.

small additions/changes to make os x and windows buildable and functional. open issues on windows time motion widgets and terminating cleanly.

MacOS X port, "home" command/button, lots of bug fixes -- into main branch!

Initialize 3 lights instead of 2.
Fix "partiview -c 'detach hide'".  It was being interpreted as "detach fullscreen"!

this enables multisampling if FLTK and the hardware support it.

Where appropriate, update references to geomview license too,
now called COPYING.geomview.

They're concatenated.  E.g. "detach fullscreen +20+20"
sets position of control window.

Make "winsize" behave sensibly for already-detached windows
(i.e. don't just leave a small subwindow in a full-screen blank field).

Once we pick a license this might change, but
in the mean time, at least the NCSA UIUC origin is noted.

Allow more subcams.

rdata/readpath command uses originating filename for path search.

Add draw-tracing hook.
Fix typo in un-ifdef'd code.

simply enable lighting and use it later, currently in specks_draw_mesh().
