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

`-Werror=array-bounds` flags when creating a new batch, possibly due to the possibility of the malloc failing (out of memory).
This PR adds an explicit `CRASHNOW` in the hope the compiler will recognise this case is not intended to be recoverable.
- Implement shadow fading when using the Orthogonal shadow mode
(like in `master`).
This allows customizing the distance at which directional shadows
start to fade away. Shadow fading will also always start at the same
distance now, regardless of the current shadow mode in use.
This is useful for enclosed levels to prevent shadows from fading
at all with a well-tuned maximum distance.
The default fade start value (0.8) results in fading happening later
in the distance compared to the previous behavior, where fading started
from the last shadow split distance (0.6 in PSSM 4 Splits and
0.1 in PSSM 2 Splits).
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.
Large groups of similar rects can be processed more efficiently using the MultiRect command. Processing common to the group can be done as a one off, instead of per rect.
Adds the new API to VisualServerCanvas, and uses the new functionality from Font, BitmapFont, DynamicFont and TileMap, via the VisualServerCanvasHelper class.
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".
