DShowCameraDeviceInteral compile error in tip

I’m getting a compile error when enableling juce camera support on VS2010, juce tip:

error C2259: ‘juce::DShowCameraDeviceInteral::GrabberCallback’ : cannot instantiate abstract class
due to following members:
HRESULT IUnknown::QueryInterface(const IID &,void **)’ : is abstract
C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\include\unknwn.h(116) : see declaration of ‘IUnknown::QueryInterface’

It must have happend in one of the last 3 commits of juce_win32_CameraDevice.cpp.

Thanks - this is fixed now.
