This part of it also get sa bit messy. You are mixing changes to the PixelFormats to "added CleanupElement DP" and so forth. It all makes it very very hard to get a comprehensive picture of the individual changes.

I know I might feel a bit picky, but I'm just extremely cautious that we keep individual changes *as small as possible*. It should be possible to have a reasonable discussion around every single changeset, so we can get as much as possible out of the community review process.
