As there seems to confusion regarding the ll branch, corell and the integration process I created some slides which hopefully communicate the current process better.

Swapchain recreation the only point missing from this list besides better error handling and some more love for the documentation. Recreation was harder to implement due to our handle based API.
Current development happens inside the ll branch which includes the integration of the other 2/3 of the process.
