parti_snapshot(): if the pattern includes '@', emit a stereo pair of images, replacing @ with L and R.

Add some redraw()s when we detach opengl window from GUI, to avoid MacOS Lion bug which left them un-refreshed.

Try to make jpeglib.h work right under Windows/MinGW.  Need to declare our own "boolean" type for some stupid reason.

Flip Y when encoding PNGs.
Always free the snapshot buffer.

   - four digits by default
   - use .png suffix if libpng available, or if unix (assumes "convert" available)
   - use .ppm suffix if WIN32 and no libpng

Add -tilt option to subcam command.

or when it changes quadbuffered-stereo status.

If there's an 8th numeric field in a .wf file, take it to be a focallen distance.

to stop animation.

Add "wait" option -- wait until end of "play".

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.

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

Build up attrs incrementally.

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

which just draw that one eye's view.  Allows easy
stereo screen snapshotting.

Important: changed sign of crosseyed stereo!
This means that positive stereo-separation values
are now correct for crosseyed (as opposed to walleyed) viewing.
To mark this incompatible change, bumped VERSION to 0.7.

picking callbacks!  Fixes broken pick-new-center after detaching view.

Properly compute window ypos from X geometry spec.

to get "detach" & "winsize +X+Y" working.  OK now??

placement of graphics window) and "detach" (sets
placement of GUI widget window).
And, try harder to make detached GUI window behave
properly when resizing.  Not yet though.

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.

for X-specific stereo code.

whether we have a patched FLTK.

but only if FL_STEREO is defined.
Otherwise use old GLX/Unix-specific way.
