Tyler Goodlet 6f00617bd3 Only do new "datum append" when visible in pixels
The basic logic is now this:
- when zooming out, uppx (units per pixel in x) can be >= 1
- if the uppx is `n` then the next pixel in view becomes occupied by
  a new datum-x-coordinate-value when the diff between the last
  datum step (since the last such update) is greater then the
  current uppx -> `datums_diff >= n`
- if we're less then some constant uppx we just always update (because
  it's not costly enough and we're not downsampling.

More or less this just avoids unnecessary real-time updates to flow
graphics until they would actually be noticeable via the next pixel
column on screen.

Tyler Goodlet 2c2c453932 Reset line graphics on downsample step..
This was a bit of a nightmare to figure out but, it seems that the
coordinate caching system will really be a dick (like the nickname for
richard for you serious types) about leaving stale graphics if we don't
reset the cache on downsample full-redraw updates...Sooo, instead we do
this manual reset to avoid such artifacts and consequently (for now)
return a `reset: bool` flag in the return tuple from `Renderer.render()`
to indicate as such.

Some further shite:
- move the step mode `.draw_last()` equivalent graphics updates down
  with the rest..
- drop some superfluous `should_redraw` logic from
  `Renderer.render()` and compound it in the full path redraw block.

Tyler Goodlet 04897fd402 Implement pre-graphics format incremental update
Adds a new pre-graphics data-format callback incremental update api to
our `Renderer`. `Renderer` instance can now overload these custom routines:

- `.update_xy()` a routine which accepts the latest [pre/a]pended data
  sliced out from shm and returns it in a format suitable to store in
  the optional `.[x/y]_data` arrays.
- `.allocate_xy()` which initially does the work of pre-allocating the
   `.[x/y]_data` arrays based on the source shm sizing such that new
   data can be filled in (to memory).
- `._xy_[first/last]: int` attrs to track index diffs between src shm
  and the xy format data updates.

Implement the step curve data format with 3 super simple routines:
- `.allocate_xy()` -> `._pathops.to_step_format()`
- `.update_xy()` -> `._flows.update_step_xy()`
- `.format_xy()` -> `._flows.step_to_xy()`

Further, adjust `._pathops.gen_ohlc_qpath()` to adhere to the new
call signature.

Tyler Goodlet 5d91516b41 Drop step mode "last datum" graphics creation from `.draw_last()`
We're doing this in `Flow.update_graphics()` atm and probably are going
to in general want custom graphics objects for all the diff curve / path
types. The new flows work seems to fix the bounding rect width calcs to
not require the ad-hoc extra `+ 1` in the step mode case; before it was
always a bit hacky anyway. This also tries to add a more correct
bounding rect adjustment for the `._last_line` segment.

Tyler Goodlet 167ae96566 Move graphics update logic into `Renderer.render()`
Finally this gets us much closer to a generic incremental update system
for graphics wherein the input array diffing, pre-graphical format data
processing, downsampler activation and incremental update and storage of
any of these data flow stages can be managed in one modular sub-system
:surfer_boi:.

Dirty deatz:
- reorg and move all path logic into `Renderer.render()` and have it
  take in pretty much the same flags as the old
  `FastAppendCurve.update_from_array()` and instead storing all update
  state vars (even copies of the downsampler related ones) on the
  renderer instance:
    - new state vars: `._last_uppx, ._in_ds, ._vr, ._avr`
    - `.render()` input bools: `new_sample_rate, should_redraw,
      should_ds, showing_src_data`
    - add a hack-around for passing in incremental update data (for now)
    via a `input_data: tuple` of numpy arrays
    - a default `uppx: float = 1`

- add new render interface attrs:
 - `.format_xy()` which takes in the source data array and produces out
   x, y arrays (and maybe a `connect` array) that can be passed to
   `.draw_path()` (the default for this is just to slice out the index
   and `array_key: str` columns from the input struct array),
 - `.draw_path()` which takes in the x, y, connect arrays and generates
   a `QPainterPath`
 - `.fast_path`, for "appendable" updates like there was on the fast
   append curve
 - move redraw (aka `.clear()` calls) into `.draw_path()` and trigger
   via `redraw: bool` flag.

- our graphics objects no longer set their own `.path` state, it's done
  by the `Flow.update_graphics()` method using output from
  `Renderer.render()` (and it's state if necessary)

Tyler Goodlet 4c7661fc23 Factor `.update_from_array()` into `Flow.update_graphics()`
A bit hacky to get all graphics types working but this is hopefully the
first step toward moving all the generic update logic into `Renderer`
types which can be themselves managed more compactly and cached per
uppx-m4 level.
