This allows Godot to automatically compress meshes to save a lot of bandwidth.
In general, this requires no interaction from the user and should result in
no noticable quality loss.
This scheme is not backwards compatible, so we have provided an upgrade
mechanism, and a mesh versioning mechanism.
Existing meshes can still be used as a result, but users can get a
performance boost by reimporting assets.
Introduces support for FSR2 as a new upscaler option available from the project settings. Also introduces an specific render list for surfaces that require motion and the ability to derive motion vectors from depth buffer and camera motion.
I couldn't tell whether this has an actual purpose and it feels more
like a debug remnant.
We also need to be able to disable vsync in the editor for the WIP
Wayland backend (in the EGL driver) as it does manual frame throttling.
PR #80296 introduced a regression because it checks if the
VK_EXT_pipeline_creation_cache_control extension has been enabled before
using it, but turns out the process is a bit more convoluted than that
(a Vulkan driver may support the extension but then say the feature is
not supported)
The Haiku platform port was never finalized, and moved to a separate repo in
Godot 3.2 days: https://github.com/godotengine/godot-platform-haiku
Sadly it didn't garner more interest there and is bitrotting. It was never
ported to Godot 4 so the bits of Haiku support left in Mono aren't useful.
The UWP platform port was never ported to the Godot 4.0+ API,
and it's now accumulating bitrot as it doesn't compile, and thus
we no longer propagate platform changes in it.
So we finally remove to acknowledge this state. There's still some
interest in reviving the UWP port eventually, especially as support
for Direct3D 12 will soon be merged, but when that happens it will
be easiest to redo it from scratch.
I wanted to add this tool for years and always forget. This command line option:
```
$ godot.exe -e --debug-canvas-item-redraw
```
Allows to see when a canvas item is redrawn. This helps find out if something
in the UI is refreshing in a way it should not. Examples as such:
* Signals causing more of the UI to redraw.
* Container resizing causes more UI elements to redraw.
* Something using a timer is redrawing all time time, which can go unnoticed.
To my surprise, the editor UI is redrawing very efficiently. There is some
weird stuff with the scene tabs, redrawing when the inspector changes but most
things for the most part are fine.
