pixels stores the pixmap data. pixelsToFree is either 0 or some memory

release callback has been called. There are two uses to pixelsToFree:
1. If pixels == pixelsToFree, then we know that the CGImageRef is done\
with the data and we can modify pixels without breaking CGImageRef's
mutability invariant.
2. If pixels != pixelsToFree and pixelsToFree != 0, then we can reuse
pixelsToFree later on instead of malloc'ing memory.
