This is also over-retaining the CGImage. However you may want to
consider creating a CGImage directly instead of going through a bitmap
context, as this gives you more flexibility in what types of image
data you can represent, as well as avoiding a trip through the kernel
to mark the memory for the bitmap context as copy-on-write.
