lawnjelly 522bce1159 Fixed Timestep Interpolation (3D)
Adds fixed timestep interpolation to the visual server.
Switchable on and off with project setting.

This version does not add new API for set_transform etc, when nodes have the interpolated flag set they will always use interpolation.

lawnjelly 3dc0e97d05 Fix incorrect buffer upload size in GLES2 draw_gui_primitive
The buffer upload size appears to have been incorrect for quite some time, which causes uploading from undefined memory.

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 a0c6d16c90 Add editor vital redraws only option
When editor continuous redraws is switched off, the editor only redraws when a redraw_request was issued by an element in the scene. This works well in most situations, but when scenes have dynamic content they will continuously issue redraw_requests.

This can be fine on high power desktops but can be an annoyance on lower power machines.

This PR splits redraw requests into high and low priority requests, defaulting to high priority. Requests due to e.g. shaders using TIME are assigned low priority.

An extra editor setting is used to record the user preference and an extra option is added to the editor spinner menu, to allow the user to select between 3 modes:

* Continuous
* Update all changes
* Update vital changes

Fabio Alessandrelli bbfe054175 [HTML5] Use compatibility function for glGetBufferSubData.
The "webgl/webgl2.h" include provides that function, but it's not
available in emscripten versions < 2.0.17 .

Since we need to support emscripten 1.39.9 (mono builds), this commit
adds a JS function in library_godot_display.js as a compatibility layer
for it, and implement glGetBufferSubData by funneling the call to that
function (so we don't have name collisions JS-side with recent emcc).

All those hacks are now moved to the platform directory instead of being
ifdefs inside the drivers implementations.

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.

- Remove unused `ENABLE_CLIP_ALPHA` from scene shader.
- Remove unused `PARTICLES_COPY` from the particles shader.
- Remove unused uniform related code.
- Shader language/compiler: use ordered hash maps for deterministic code generation (needed for caching).

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

clang-format: Disable alignment of operands, too unreliable
Sets `AlignOperands` to `DontAlign`.

`clang-format` developers seem to mostly care about space-based indentation and
every other version of clang-format breaks the bad mismatch of tabs and spaces
that it seems to use for operand alignment. So it's better without, so that it
respects our two-tabs `ContinuationIndentWidth`.

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

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.

This backports the high quality glow mode from the `master` branch.

Previously, during downsample, every second row was ignored.
Now, when high-quality is used, we sample two rows at once to ensure
that no pixel is missed. It is slower, but looks much better and has
a much high stability while moving.

High quality also takes an additional horizontal sample the width of the
horizontal blur matches the height of the vertical blur.

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

Improve the shader error console output
This makes the line gutter look more like an actual line gutter,
which makes it less confusing.
