Option to disable terminal's first/status line (with the Blinka snake)

[HilmarSt]

I'm using displayio with small OLED displays, e.g. a SSD1306 based one with 64 x 32 px.
Example code:

import displayio
displayio.release_displays()
import board, busio
i2c = busio.I2C(board.GP3, board.GP2) # SCL, SDA
from i2cdisplaybus import I2CDisplayBus
display_bus = I2CDisplayBus(i2c, device_address=0x3C)
import adafruit_displayio_ssd1306
adafruit_displayio_ssd1306.SSD1306(display_bus, width=64, height=32)
print("0123456789")

The display shows 3 lines of text, where the first 2 lines are occupied by the Blinka logo and the Circuitpython version.
Only the third line is usable and shows the wanted output.

I would like to request a possibility to disable the logo/version output, such that the whole display area is available for text output.

Eventually related to #10445 and https://forums.adafruit.com/viewtopic.php?p=1058992&sid=0105da6d9bd0e527909672a7c0fb8fbb#p1058992

I've tried this in boot.py without success :

import supervisor
supervisor.status_bar.console = False
supervisor.status_bar.display = False

Agreed with this ticket that there should be a neat way of doing this.

Workaround:

display.root_group[1].hidden = True  # logo
display.root_group[2].hidden = True  # status bar
supervisor.reset_terminal(display.width, TERMINAL_HEIGHT)
display.root_group[0].y = 0

Where TERMINAL_HEIGHT is the number that makes supervisor_start_terminal set scroll_area->pixel_height to the height of the screen? Needs to be more than display.height but not sure how much.

The default CircuitPython terminal is meant to be the structure we'd like it to be. If you'd like just a terminal, then you can create your own full size one. @FoamyGuy just updated the Terminal docs with example code to do this. See #10698
