The fact that the relationship between
machine position and pixel index is not linear
means we cannot simply rely on comparing
the previous position to the next machine position. i.e derivative of E_AXIS
Because around the max amplitude of the triangle wave
the slope will suddenly change sign and will create a deadzone
which has width 2*mm_per_pixel.
For MMU2S this is ~10mm (or two pixels).
Instead we should split the moves.
And only plan the 2nd move once we're
at the top of the triangle wave. That way we don't really care about the position delta.
Now we just calculate the current y(x)
position relative to current position and divide by mm_per_pixel.
If there is a delta measured with unit 'pixel' then that means
its time to render the next pixel.
This solution seems to work well so far on my end.

This fixes an issue where sometimes
not all 20 pixels are rendered.
It is better to render 1 too many pixels (sometimes), rather than rendering too few.

In case we are running a retry, the firmware
should clear the old rendering before
starting on a new one

* M600 used 1°C threshold, which may increase the waiting time a bit
* Wizard used 3°C
Sync both to use TEMP_HYSTERESIS for consistancy
No change in memory footprint
Use 5°C threshold to be consistant with other parts
of the firmware.
Relying on 95% of the target temperature creates
a dependency on the temperature:
PLA: Target = 215°C, threshold = 10.75°C
PETG: Target = 230°C, threshold = 11.5°C
ABS: Target = 255°C, threshold = 12.75°C
ASA: Target =260°C, threshold = 13.0°C
PC: Target = 275°C, threshold = 13.75°C
My proposal is we instead use a constant
TEMP_HYSTERESIS = 5, which is consistent with
M109, and behavior when restoring print from RAM
and some of the MMU code (like unload function)

This commit adds the ability for the firmware to dim and wake the
backlight when LCD updates are disabled. Such as in the MMU error screen
or when rendering full screen messages which typically
disable the LCD updates to prevent the status screen from rendering.
Fixes#2777

Flash: -26 bytes

It may be useful to view the Sensors menu
while the toolchange loading test is taking
place. For example to see if the reading is flickering
The firmware needs to call lcd_update(0) to update the screen rendering.
