This fix works in both GLES3 and GLES2.
The rendering formula in the shader was adjusted to further improve the
sharpness/antialiasing quality balance.

On some hardware, modifying gl_FragColor multiple times can cause large performance drops. This PR writes to a standard temporary variable instead, and copies across to gl_FragColor once only at the end of the fragment shader.
This could potentially lead to large gains in performance on affected hardware.
Certain glGet operations require 64 bit versions according to the GLES spec.
The previous code was susceptible to overflow bugs, especially running under ANGLE.
Adds optional hierarchical culling to the 2D rendering (within VisualServer).
Each canvas item maintains a bound in local space of the item itself and all child / grandchild items. This allows branches to be culled at once when they don't intersect a viewport.
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".
Backported from #70885.
This mostly reverts the approach in #62628, which now the problem is better scoped, looks overengineered and instead focuses on the few cases where there's something to take care of.

This adds these as new Built-Ins to Spatial Shaders
* Object's Position in World Space
* Camera Position in World Space
* Camera Direction in World Space
* Object's Position in View Space
Adds special logic for handling skeleton bounding rect updates. Previously these were never being updated because the canvas item is never set to "rect_dirty".
