Drawing shapes requires degrees mode

[anderjef]

Using the dot or circle functions while in radians mode appears to freeze the program for a number of seconds as it draws small lines for dot (instead of a dot) and heads out to a point and back for circle (instead of a circle or any regular polygon) before continuing to run the rest of the program. Using a Circuit Playground Bluefruit with TFT Gizmo.

Code to reproduce:

import board
import busio
import displayio
import adafruit_turtle

displayio.release_displays()
spi = busio.SPI(board.SCL, MOSI=board.SDA)
display_bus = displayio.FourWire(spi, command=board.TX, chip_select=board.RX)
display = ST7789(display_bus, width=240, height=240, rowstart=80, backlight_pin=board.A3, rotation=180)
turtle = adafruit_turtle.turtle(display)

turtle.radians()
turtle.pendown()
turtle.dot(10)
turtle.circle(50)

The workaround is to reset mode with turtle.degrees() before attempting to call either dot or circle.
