lawnjelly c6a428b3d6 GLES2 fix octahedral half float unpacking
The strides in _unpack_half_floats() were incorrectly calculated in the case where octahedral normals and tangents were in use.

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.

Omar El Sheikh 733a84f7a4 GLES2 Compression on Blend Shapes Fix
When compressed vertex positions are used in a blend shapes mesh, we
need to make sure we set the w-component of the position vector to 1.0

When octahedral compression is used on normals/tangents, they need to be
converted to cartesian floats to be used for blend shapes

This conversion also changes the number of components of that vertex
attribute, which caused issues because previously there was an
assumption that you had the same number of components in the blend shape
buffer as you did in the original mesh's buffer (which is not true for
oct norm/tang)

lawnjelly 614dc363ab Fix GL buffer upload size bugs
Wrapper functions for uploading buffers to OpenGL take all sizes and offsets in bytes. Some buffer sizes are specified as units (e.g. float) so require conversion to bytes when calling the buffer upload functions.

Two such bugs have been fixed in blendshapes, and parameter names and comments have been changed to emphasize that sizes should be in bytes.

In addition DEV_ASSERTS in the upload wrappers have been changed to ERR_FAIL.

lawnjelly b15ad8e786 Fix for S3TC on Android and IOS devices
On some platforms, exporters are prevented from exporting S3TC textures. This causes problems if the .import file contains a reference to such a texture - the exported project will attempt to load the S3TC, fail, and probably crash.

This PR prevents this problem by faking lack of hardware support for S3TC on the affected platforms. This prevents the engine attempting to load the S3TC and avoids the problem.

Omar El Sheikh bf5b2f48e6 Re-fix Disabling Half Floats on iOS
A previous change missed setting a flag that specified whether half
floats were being used on vertex positions when in the GLES2 driver

This caused errors with the vertex buffer when platforms (specifically
iOS) which do not properly support half float vertex attributes on
GLES2, try to remapt the vertex buffer to stop using half floats
(in this case that remapping never happened and caused artifacts)

Re-enable setting that flag to fix rendering issues on these platforms

Fernando Cosentino cc8846bef6 Added material_overlay property to MeshInstance
Applying overlay materials into multi-surface meshes currently
requires adding a next pass material to all the surfaces, which
might be cumbersome when the material is to be applied to a range
of different geometries. This also makes it not trivial to use
AnimationPlayer to control the material in case of visual effects.
The material_override property is not an option as it works
replacing the active material for the surfaces, not adding a new pass.

This commit adds the material_overlay property to GeometryInstance
(and therefore MeshInstance), having the same reach as
material_override (that is, all surfaces) but adding a new material
pass on top of the active materials, instead of replacing them.

Implemented in rasterizer of both GLES2 and GLES3.

Omar El Sheikh 8a43b222c7 Fix Vertex Attribute Specification Octahedral
For octahedral compressed normals/tangents, we use vec4 in the shader
regardless of whether a normal/tangent does/doesn't exist

For the case where we only have a normal vector, we need to specify that
there are only two components being used when calling glVertexAttrib

Before we would always specify that there were 4 components, and used
offsets to determine where in the vertex buffer to read data from but
this doesn't work on all platforms

Backport new 3D point light attenuation as an option
This provides more realistic lighting with a very small performance cost.
The option is available in both GLES3 and GLES2, and can be enabled in
the Project Settings. This goes well with the ACES Fitted tonemapping mode
that was recently added.

When enabled, this also makes upgrading Godot 3.x projects to Godot 4.0 easier,
since lighting in 3.x will better match how it'll look in Godot 4.0.

Omar El Sheikh a63028e172 Fix Octahedral/Split Stream Options
Update mesh_surface_get_format_stride and
mesh_surface_make_offsets_from_format to return an array of offsets and
an array of strides in order to support vertex stream splitting

Update _get_array_from_surface to also support vertex stream splitting

Add a condition on split stream usage to ensure it does not get used on
dynamic meshes

Handle case when Tangent is compressed but Normal is not compressed

Make stream splitting option require a restart in the settings

Update SoftBody and Sprite3D to support and use strides and offsets
returned by updated visual_server functions

Update Sprite3D to use the dynamic mesh flag

Omar El Sheikh f0de7ec2b6 Align Vertex Buffer to 4 Bytes
With the octahedral compression, we had attributes of a size of 2 bytes
which potentially caused performance regressions on iOS/Mac

Now add padding to the normal/tangent buffer

For octahedral, normal will always be oct32 encoded
UNLESS tangent exists and is also compressed
then both will be oct16 encoded and packed into a vec4<GL_BYTE>
attribute

Omar El Sheikh d274284069 Octahedral Normal/Tangent Compression
Implement Octahedral Compression for normal/tangent vectors
*Oct32 for uncompressed vectors
*Oct16 for compressed vectors

Reduces vertex size for each attribute by
*Uncompressed: 12 bytes, vec4<float32> -> vec2<unorm16>
*Compressed: 2 bytes, vec4<unorm8> -> vec2<unorm8>

Binormal sign is encoded in the y coordinate of the encoded tangent

Added conversion functions to go from octahedral mapping to cartesian
for normal and tangent vectors

sprite_3d and soft_body meshes write to their vertex buffer memory
directly and need to convert their normals and tangents to the new oct
format before writing

Created a new mesh flag to specify whether a mesh is using octahedral
compression or not
Updated documentation to discuss new flag/defaults

Created shader flags to specify whether octahedral or cartesian vectors
are being used

Updated importers to use octahedral representation as the default format
for importing meshes

Updated ShaderGLES2 to support 64 bit version codes as we hit the limit
of the 32-bit integer that was previously used as a bitset to store
enabled/disabled flags

Omar El Sheikh 7f8487a900 Split Vertex Position and Attribute Streams
Implemented splitting of vertex positions and attributes in the vertex
buffer

Positions are sequential at the start of the buffer, followed by the
additional attributes which are interleaved

Made a project setting which enables/disabled the buffer formatting
throughout the project

Implemented in both GLES2 and GLES3

This improves performance particularly on tile-based GPUs as well as
cache performance for something like shadow mapping which only needs
position data

Updated Docs and Project Setting

Add support for contrast-adaptive sharpening in 3D (GLES3 only)
This is an older, easier to implement variant of CAS as a pure
fragment shader. It doesn't support upscaling, but we won't make
use of it (at least for now).

The sharpening intensity can be adjusted on a per-Viewport basis.
For the root viewport, it can be adjusted in the Project Settings.

Since `textureLodOffset()` isn't available in GLES2, there is no
way to support contrast-adaptive sharpening in GLES2.
