Note that this was actually not very difficult, compared to dealing with the client sizing logic, which was teetering on the brink of total collapse. I may have messed something up while trying to support it here (mainly related to emu-space and client-space padding). There were many assumptions that the core's videoProvider would remain sensible, which this "core screen control" system subverts. The padding and sizing was added after I designed the pipeline specifically for this, so the padding and sizing is not handling it very well. Nonetheless, I think it works.
