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

"inertia on/off" and "detach [fullscreen]" commands.

in detached mode.

and into partiview.cc, using new parti_add_commands hook.

apparently -- ctrl-K trick doesn't work so well.

pp_stepper needs to update all windows, not just gview.
H-R diagram toggles...

Add new -c "command string" cmd-line option.
Use findfile() to find ~/.partiviewrc and ./.partiviewrc.
Let command-line "-geometry" override initial "winsize".

Both are in .cf (i.e. data-command) form.
Make winsize command work even if we haven't created the window yet --
just save requested size and set it later.

If creating, and object name not of g<N> form, then make an alias too.

Stick current alias on logslum slider -- there's room enough.

New pickrange.
Don't forget to redraw after "Backtrip".

Don't show time-control bar unless some object has a nonzero

Keyboard shortcuts "<" and ">" stop animation.
Shortcuts "{" and "}" start animation (backwards & forwards).

Fix some clock bugs.
Middle- or right-click on "step" buttons advance by .1 or 10 times normal step.
Tie step to speed: step = 0.1sec * speed.

Lots of changes to support new time flow and additional
time-related GUI.  Probably not all there but at least somewhat usable.
