Please provide names for the arguments since it's no longer obvious from the
function name what it means.

I also suggest renaming to applyViewportDeltas since they're all deltas.

Also, looking forward to when the scroll delta becomes unused, how about making
it the last argument and setting a default value for it?  This will make
removing it less painful in the future.

I'd rather leave this for now, I'll deal with the pain in the future :)
