Examples
font_file <- system.file("fonts/spleen/spleen-8x16.hex.gz", package = "bittermelon")
font <- read_hex(font_file)
bm_widths(font) # every glyph in the font is 8 pixels wide
bm_heights(font) # every glyph in the font is 16 pixels high
corn <- farming_crops_16x16()$corn$portrait
bm_widths(corn)
bm_heights(corn)
