bc607fb607 Fix signed distance field font rendering 
This fix works in both GLES3 and GLES2.

The rendering formula in the shader was adjusted to further improve the
sharpness/antialiasing quality balance.

ed3d029f5d GLES2 / GLES3 - Use gl_FragColor temporary 
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.

6ff370030a Fix glGet overflows by using 64 bit versions 
Certain glGet operations require 64 bit versions according to the GLES spec.
The previous code was susceptible to overflow bugs,  especially running under ANGLE.

857d884026 Initialize GLWrapper earlier in Storage::initialize() 
Make sure `GLWrapper` is initialized before `glActiveTexture` is called by other parts of the storage initialize(), to prevent benign warnings.

b777a9e5f9 Canvas item hierarchical culling 
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.

One Copyright Update to rule them all 
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.
