Minor notice that screen coordinates use action.x instead of action.screen_x. This is a bit confusing, so unless there are other reasons to keep the current naming convention (other than backwards compatibility) it would be nice to switch the two names.

I agree. It is confusing. I'll try to fix it for the next release I make!
