This had some not-so-good consequences, like inability to map anything
in VR, and sometimes empty MultiMappings would result that we could end
up asserting on before the previous commit.
Unfortunately, the default values from the configs are not exposed
outside Config.cpp, so there's duplication.
Need to figure out how to do fix that, but it's out-of-scope for this
PR.
* ControlMapper: Change the callbacks to be more suitable for the upcoming refactor.
* SetAllButtons: Separate bits to set and bits to clear.
* Oops, missed committing some files somehow
* Wrap the display globals in a struct
Makes it easier to search/replace these, for future refactorings.
* Some renaming
* Qt buildfix, also fix the Qt build on Mac (got broken with battery changes)
* Attempt at buildfixing ios
* UWP buildfix
I think its benefit is absolutely tiny if any, and causes a lot more
problems than it's worth. Bye.
Note that this isn't the rendering resolution selector, that will of
course still be there, but it's the "hardware scaler" resolution.
