Now, the only #ifdef KIRA/WARP needed in partibrains.c are
the data-command initialization routines.  All others,
including control-command parsing and specialized drawing,
is now via a function table.

Don't try to allocate in local memory -- use shmem after all.

Put colorseq/sizeseq/threshseq invalidation in kira_parti, not here,
since we needn't do it when warping.
By default, clock range is whatever it had been set to before.

Add seed counter to struct stuff.

Initialize all dynamic-data stuff explicitly.

we're not using them yet.

get_dsp_context ad MAXDSPCTX.

Ellipsoids allow 3-component (Rx Ry Rz) orientation numbers too.
st->dyndata doesn't mean we should trash the anima[][] specklist.
Need to keep it intact for warping.

So if we're off the end, or if a null warp is in effect,
don't mess with it.

differential rotation function.  See "warp" command in partibrains.c.

Finally parse snapshot arguments properly...?

for good accuracy throughout the range.

snapshot/snapset.  Not actually implemented yet.
Add "clipbox hide".  This (a) doesn't display the big yellow box
and (b) doesn't enable OpenGL clipping -- just whatever object culling
the draw routine does anyway.
specks_draw_mesh() now pays attention to drawing style (solid/line/plane/point).
When drawing ellipsoids, disable blending altogether if bgcolor != 0.
Small, distant labels now disappear by default.  To get the old
draw-tiny-line behavior, use a negative "labelmin" value.

Can't actually do such rendering yet.

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

Accept ~/file and ./file without path searching.

doesn't already have one.

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.
