Also, don't forget that CGFloat is sometimes float and sometimes double,
depending if you're building for 32 or 64 bit. This can be annoying
when you want to use constants like '0.0f'. Should one use the 'f' or
not? If you don't, you'll get warnings in 32 bit about implicit 64 to
32 bit conversions.
