As many open source projects have started doing it, we're removing the
current year from the copyright notice, so that we don't need to bump
it every year.
It seems like only the first year of publication is technically
relevant for copyright notices, and even that seems to be something
that many companies stopped listing altogether (in a version controlled
codebase, the commits are a much better source of date of publication
than a hardcoded copyright statement).
We also now list Godot Engine contributors first as we're collectively
the current maintainers of the project, and we clarify that the
"exclusive" copyright of the co-founders covers the timespan before
opensourcing (their further contributions are included as part of Godot
Engine contributors).
Also fixed "cf." Frenchism - it's meant as "refer to / see".
CanvasItemEditor:
- p_result == ADD_MOVE is always true in this switch-clause
- both parts of the if-else-clause do the same thing and simplified an affine_inverse call
ControlEditorToolbar:
- private function ControlEditorToolbar::_anchor_to_position is used nowhere. Looks like
copy and paste from CanvasItemEditor::_anchor_to_position
ScrollContainer:
- screen_is_touchscreen is always true, because otherwise the function already returned
TextLine:
- both parts of the if-else-clause do the same thing and simplified return statement
Using this command:
```
find -name "thirdparty" -prune -o -name "*.h" -exec sed -i {} -e '/return /! s/\t\([A-Za-z0-9_]* \*[A-Za-z0-9_]*\)\;/\t\1 = nullptr;/g' \;
```
And then reviewing the changes manually to discard the ones that don't
seem correct/safe/good (notably changes to `core` unions).
Removes some unnecessary includes from `editor_node.h`, and instead add
those where they're used.
Removes unnecessary `editor_node.h` includes in various editor classes.
Renames `dynamicfont` to `dynamic_font` in a couple files.
Misc cleanup while jumping through that rabbit hole.
