This commit makes 2D camera limits have a well defined behavior for cases when the limits are smaller than the screen rect.
Presently the RIGHT and TOP limit take prescidence simply because they are applied second. This change adjusts behavior to split the difference in cases where both the LEFT/RIGHT or TOP/BOTTOM limits would both apply.
GLOBAL_GET is an expensive operation which should not be used each frame / tick.
This PR adds macros which do a cheaper revision check, and only call the expensive GLOBAL_GET when project settings have changed.

Allows a non-interpolated particle system to closely follow an interpolated target without tracking ahead of the target, by performing fixed timestep interpolation on the particle system global transform, and using this for emission.

Adds fixed timestep interpolation to the rendering server (2D only).
Switchable on and off with a project setting (default is off).

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".
Camera2D has follow smoothing to interpolate towards a target position, but no rotation smoothing to align with the target rotation.
This adds rotation smoothing directly into the Camera2D API by having two new properties:
- `rotation_smoothing_enabled`
- `rotation_smoothing_speed`
Affects a lot of classes. Very thoroughly checked signal connections and deferred calls to this method, add_do_method/add_undo_method calls, and so on.
Also renames the internal `_update_callback()` to `_redraw_callback()` for consistency.
Just a few comments have also been changed to say "redraw".
In CPUParticles2D, there was a private variable with the same name. It has been renamed to `do_redraw`.
