correcting_anchor_point for bitmap_label Upwards and Downwards direction

[jposada202020]

This will correct some small glitches with the anchor point for bitmap_label for the UPR and DWR direction

Test Code

import displayio
import board
from adafruit_display_text import bitmap_label
from adafruit_bitmap_font import bitmap_font

display = board.DISPLAY

main_group = displayio.Group(max_size=10)
MEDIUM_FONT = bitmap_font.load_font("fonts/Helvetica-Bold-16.bdf")
LINE_HOR = displayio.Bitmap(4, display.height, 2)
LINE_VER = displayio.Bitmap(display.width, 4, 2)
COLOR = 0x990099
palette = displayio.Palette(2)
palette[0] = 0x004400
palette[1] = 0x00FFFF


text_area_UPR = bitmap_label.Label(MEDIUM_FONT,
                                   text="Upwards-1.0",
                                   label_direction="UPR",
                                   background_color=COLOR,
                                   anchored_position=(200, 200),
                                   anchor_point=(1.0, 1.0),
                                    )

                                    anchored_position=(230, 200),
                                    anchor_point=(1.0, 0.5),
                                    )

                                    text="Upwards-0.0", label_direction="UPR",
                                    background_color=COLOR,
                                    anchored_position=(260, 200),
                                    anchor_point=(1.0, 0.0),
                                    )

line_ver = displayio.TileGrid(LINE_VER, pixel_shader=palette, x=0, y=200)
line_hor = displayio.TileGrid(LINE_HOR, pixel_shader=palette, x=200, y=0)
main_group.append(line_ver)
main_group.append(line_hor)

main_group.append(text_area_UPR)
main_group.append(text_area_UPR2)
main_group.append(text_area_UPR3)
display.show(main_group)

while True:
    pass
