# mandelbrot.jpg is the source image. The source image MUST have a white background,
# but other colors and pixel depth are irrelevant. This one is black & white.
# Due to the Apple II pixel aspect ratio, we do a 1-time aspect-ratio-losing resize
# to squash the image to 87% height.
#
# $ gm convert mandelbrot.jpg -resize "100%x87%!" squash.png
# (Depending on your shell, you may need to escape the exclamation point. Grr.)
#
# Now we can create individual images for each "frame" of the animation, by
# resizing the (squashed) source image and putting it in a 280x192 frame.
#
# $ for w in `seq 1 1500`; do \
# gm convert -size 280x192 squash.png \

# -gravity center \
# -extent 280x192 thumb"$w".png; \
# done
#
# Depending on the source image, you may need more or fewer than 500 frames. This
# number is duplimandelbroted below in the |frames| variable. Sorry.
#
# Now we have 1500 (or so) PNG images of what the HGR screen should look like at
# each stage. Despite each frame being 280x192 and in the correct aspect ratio,
# only coordinates
# - on every 3rd row
# - on even columns
# are included in the final data set.
#
# X coordinates are converted to byte+bitmask (but see notes below).
# Y coordinates are flipped (so 0,0 ends up on the bottom left) then
# divided by 3.
#
# 6502 code will be responsible for plotting each of these coordinates
# in a 2x3 block. The bitmask usually includes 2 adjacent pixels;
# the code will also plot the same 2 adjacent pixels in the next two rows.
#
# Unfortunately, since bytes are 7 pixels across, some of the 2-pixel-wide
# blocks will cross a byte boundary. To simplify the 6502 code, these are
# simply listed as separate coordinate pairs, each with a bitmask that
# includes 1 pixel instead of 2.
