Clear up a potential misunderstanding for new users.
When I first read this documentation, it left me with the impression that there's a `/root` viewport which lives inside of the window object. This false lesson was reinforced by the existing of both `get_window()` and `get_viewport()` in the API.
This allows users to leave comments on pages that don't have
`:allow_comments: False` somewhere in the page's source.
Both manual and class reference pages can receive comments.
Index pages cannot have comments, as discussion should occur on "leaf" pages.
GitHub Discussions is used as a backend on the same repository. This means
that Discussions *must* be enabled on godotengine/godot-docs before this
commit is merged to `master`. Users can choose to use the "Custom" watch
mode if they don't want to get notifications for discussion updates,
but still get notifications for issue and pull request updates.
User comments are intended to be used for the following purposes:
- Add a clarification or correct something in the documentation,
without having to open a pull request. Contributors are encouraged to
take a look at discussions from time to time, and see if there's information
worth incorporating in the pages themselves. Don't forget to reply to
the comment when doing so :)
- Mention a workaround for a common issue.
- Link to useful third-party resources that are relevant to the current page,
such as tutorials or add-ons.
User comments should *not* be used for technical support. Other community
platforms should be used for that.
Page-to-discussion matching is done using the `pagename` Sphinx variable,
which is independent of the Godot version and documentation language.
Being independent of the Godot version allows keeping old comments
when the Godot version changes, while also allowing users from `/stable`
and `/4.1` to "see" each other in discussions.
See https://giscus.app for more information.
Stuttering is more common on Linux when playing in windowed mode,
regardless of how powerful the hardware is. This can occur even if
compositing is disabled in the window manager (as tested on KWin).
The viewport tutorial:
https://docs.godotengine.org/en/latest/tutorials/rendering/viewports.html
did not work for Godot 4- as instead of get_data() from
Texture one should use get_image() from Texture2D.
Also setting a texture didn't work as documented, fixed too.
Tested by using the code on a simple scene with a sprite.
This should be backported to 4.0 branch, but not previous ones.
Fixes#7162
- Mention how to change each stretch-related property at runtime
from a script.
- Link to the Multiple Resolutions and Aspect Ratios demo project.
- Remove outdated Shrink section (this is no longer present in 4.0,
as it was replaced by Scale).
- Add section on input lag, containing project and hardware/OS
configuration recommendations.
- Remove outdated advice about graphics drivers on Linux.
- Mention that compositing can sometimes be disabled on Linux for
better performance.
- Wrap to 80 characters.
