Hello again,

My vacations were sadly cut short, but this allowed me to upload a working sample sooner. In the end, using `fmt.loadTopDown` didn’t work for some reason, but I’ve managed to flip the texture another way.

As I mentioned [here](https://discourse.libcinder.org/t/directshow-hap-implementation/1099/6), the majority of the port was done by @dave.

The sample can be downloaded [here](https://github.com/lightact/HAP-Cinder).

Thanks again for all your help!  
Mitja
