Tyler Goodlet 99965e7601 Only draw mx/mn line for last uppx's worth of datums
When using m4, we downsample to the max and min of each
pixel-column's-worth of data thus preserving range / dispersion details
whilst not drawing more graphics then can be displayed by the available
amount of horizontal pixels.

Take and apply this exact same concept to the "last datum" graphics
elements for any `Flow` that is reported as being in a downsampled
state:

- take the xy output from the `Curve.draw_last_datum()`,
- slice out all data that fits in the last pixel's worth of x-range
  by using the uppx,
- compute the highest and lowest value from that data,
- draw a singe line segment which spans this yrange thus creating
  a simple vertical set of pixels which are "filled in" and show the
  entire y-range for the most recent data "contained with that pixel".

Tyler Goodlet a66934a49d Add `Curve` sub-types with new custom graphics API
Instead of using a bunch of internal logic to modify low level paint-able
elements create a `Curve` lineage that allows for graphics "style"
customization via a small set of public methods:
- `Curve.declare_paintables()` to allow setup of state/elements to be
  drawn in later methods.
- `.sub_paint()` to allow painting additional elements along with the
  defaults.
- `.sub_br()` to customize the `.boundingRect()` dimensions.
- `.draw_last_datum()` which is expected to produce the paintable
  elements which will show the last datum in view.

Introduce the new sub-types and load as necessary in
`ChartPlotWidget.draw_curve()`:
- `FlattenedOHLC`
- `StepCurve`

Reimplement all `.draw_last()` routines as a `Curve` method
and call it the same way from `Flow.update_graphics()`

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)
