This section illustrates incorrect grid usage and common mistakes to avoid:
1. Note that glyphs that are two units wide must not cross major (magenta) grid lines. Glyphs that are one unit wide must not cross major or minor (green) grid lines.
2. Do not connect glyphs at only half their height or width. Glyphs must share either their full height or full width.
3. Ensure tiles with glyphs are always be adjacent or diagonal to another glyph.
4. Do not place the same background colors next to each may cause tiles to merge visually.
