Memory leak (see attached valgrind.log)

## Issue or Feature

I'm using node-canvas for a project and it looks like there's some memory leak in the code, because the memory consumption of my app grows until the process is killed by the kernel due to an OOM. I've checked my own code using heap snapshots and the heap is around 20MB and stable.

## Steps to Reproduce
I'm trying to isolate the offending part of the code, but I don't have it yet. I did run the program through valgrind and here's the log:
