* Reduce code duplication in src\openrct2\interface\Window.cpp
`window_resize_gui_scenario_editor` was a subset of `window_resize_gui`
* Reduce code duplication in src\openrct2\network\Twitch.cpp
Both `GetFollowers()` and `GetMessage()` were very similar
* Reduce code duplication in src/openrct2/world/SmallScenery.cpp
`map_place_non_scenery_clear_func` and `map_place_scenery_clear_func` did basically the same thing, with a single branch difference
* Reduce code duplication in src/openrct2-ui/windows/TopToolbar.cpp
Make `top_toolbar_tool_update_scenery_clear` call `top_toolbar_tool_update_land_paint` and then do the additional differing calculation it did.
* Use ScreenCoordsXY for window_create function
* Use ScreenCoordsXY for window_find_from_point function
* Use ScreenCoordsXY for window_find_widget_from_point
* Use ScreenCoordsXY for ride_contruction_tool*
* Use ScreenCoordsXY for window_event_tool*
* Use ScreenCoordsXY for window_event_scroll_mouse*
* Use ScreenCoordsXY for remaining window_event*
* Use ScreenCoordsXY for window_(set|move)_position
I went over the commits ab7f22f..8726712 (bulk format commits for game actions to management inclusive) and corrected all mistakes I found. Most of them have to do with arrays missing trailing commas, making clang-format indent the entire array or not add breaks between the values.
Clang-format sees the text behind `#pragma region` as code and formats it. Instead of stating the copyright and date there, it's now in the comment block right below it. The text "Copyright" is left in the `#pragma region` line, as clang-format sees it as a single identifier.
I took the opportunity to normalize the dates, and add the copyright notice to the source files where it was missing them (except for third-party and the generated resources.h file).
It's possible that widgets are arranged in such a way that the roder of buttons matches the order of tool-size widgets or steppers. Now instead of just checking the types, also their content will be checked.
