Fix shape images

[eltoder]

• Make all shapes the same size
• Make sure shapes are centered in cards
• Make squiggles rotationally symmetric
• Make diamonds symmetric (it's slightly chipped at the top and the bottom and skewed)
• Fix cards with 4 shapes, especially the small cards (it looks like they slightly don't fit and get smaller)
• Try using zoomed patterns for small cards
• Optimize paths
