issue

Hi,

It is a cool library - great work!

However, we were using FBBitmapFont/View repeatedly [i.e. changing the text] and it is causing very large spike in memory - suddenly it grows to 50MB, 100MB and 200MB before it is killed by iOS.

1. We have tested a few times and narrowed it down to this component. It happens very frequently if you change size of text and adjust the number of padding dots so it is centered.
2. I've looked at Instruments and it is showing very huge single allocations [39MB, etc] with many CG calls.
3. I've looked at the drawRect code and found a similar post here:

   Most likely something like this is going on, but I am not a CoreGraphics expert.
4. I also tested for potential UIGraphicsGetImageFromCurrentImageContext leak but it doesn't help:
   @autoreleasepool {

   and ensure it runs on main thread

Thanks in advance if you can look into it. Is a nice library.
