Tyler Goodlet 9572280553 Kill the tractor tree on window close.
This makes it so you don't have to ctrl-c kill apps.
Add in the experimental openGL support even though I'm pretty sure it's
not being used much for curve plotting (but could be wrong).

Tyler Goodlet daa429f7ca Put fsp plotting into a couple tasks, startup speedups.
Break the chart update code for fsps into a new task (add a nursery) in
new `spawn_fsps` (was `chart_from_fsps`) that async requests actor
spawning and initial historical data (all CPU bound work).  For multiple
fsp subcharts this allows processing initial output in parallel
(multi-core). We might want to wrap this in a "feed" like api
eventually. Basically the fsp startup sequence is now:
- start all requested fsp actors in an async loop and wait for
  historical data to arrive
- loop through them all again to start update tasks which do chart
  graphics rendering

Add separate x-axis objects for each new subchart (required by
pyqtgraph); still need to fix hiding unnecessary ones.
Add a `ChartPlotWidget._arrays: dict` for holding overlay data distinct
from ohlc. Drop the sizing yrange to label heights for now since it's
pretty much all gone to hell since adding L1 labels. Fix y-stickies to
look up correct overly arrays.

Tyler Goodlet af61611801 Add initial selection box interaction
Requires decent modification of the built-in ``ViewBox``.
We do away with the zoom functionality for now and instead just add
a label full of some simple stats on the bounded data.

Tyler Goodlet cc88300ac5 Fix L1 updates to be like TWS
I think this gets us to the same output as TWS both on booktrader and
the quote details pane. In theory there might be logic needed to
decreases an L1 queue size on trades but can't seem to get it without
getting -ves displayed occasionally - thus leaving it for now.

Also, fix the max-min streaming logic to actually do its job, lel.

Tyler Goodlet 73e54a2259 Add L1 labels wrapper type
Start a simple API for L1 bid/ask labels.
Make `LevelLabel` draw a line above/below it's text (instead of the
rect fill we had before) since it looks much simpler/slicker.
Generalize the label text orientation through bounding rect
geometry positioning.

Tyler Goodlet e65f511648 Draw flat line on every new time step
Until we get a better datum "cursor" figured out just draw the flat bar
despite the extra overhead. The reason to do this in 2 separate calls is
detailed in the comment but basic gist is that there's a race between
writer and reader of the last shm index.

Oh, and toss in some draft symbol search label code.

Tyler Goodlet 119196f2ff Scale level label correctly to small(er) fonts
Not sure what fixed it exactly, and I guess we didn't need any relative
DPI scaling factor after all. Using the 3px margin on the level label
seems to make it look nice for any font size (i think) as well.

Gonna need some cleanup after this one.

Tyler Goodlet 23672fc22b Rework axes types, sizing stuff
Make our own ``Axis`` and have it call an impl specific ``.resize()``
such that different axes can size to their own spec. Allow passing in a
"typical maximum value string" which will be used by default for sizing
the axis' minor dimension; a common value should be passed to all axes
in a linked split charts widget. Add size hinting for axes labels such
that they can check their parent (axis) for desired dimensions if
needed.

Tyler Goodlet 89d48afb6c Size axis labels based on text contents
Compute the size in pixels the label based on the label's contents.
Eventually we want to have an update system that can iterate through
axes and labels to do this whenever needed (eg. after widget is moved
to a new screen with a different DPI).
