IOSurface creation failed:

First of all, thank you for this great app
I've updated to latest OF in a fork here: https://github.com/dimitre/VisionOSC/tree/latest

I'm using body detection at 60fps, but after a while it gets an error:
```
IOSurface creation failed: e00002be parentID: 00000000 properties: <private> (likely per client IOSurface limit of 16384 reached)
```
maybe some resorce is not being released properly
