Firstly thank you as this is a great service (so please keep up the great work!).
I'm using the "hexa isogrids" as placeholder for profile images, but I've noticed they don't fill the entire canvas.
E.g. if I put a 32x32 hexa isogrid on my page, after measuring the resulting pixels in photoshop, it's more like 27x30.
Any ideas? Would this be an easy one to fix?
