Display freelook speed and zoom in units in the 3D editor viewport

Normalise p_up_direction vector in move_and_slide()

move_and_slide_with_snap() and fix tolerance in
move_and_slide_with_snap() max floor angle.

Now that the 3D editor grid is infinite and adjusts its step automatically,
this helps people get a better sense of scale when moving around in the
3D viewport.

This also fixes the indicator bar drawing on hiDPI displays.

Check pointers against nullptr.

* Added helper functions to Skeleton3D for converting transforms from bone space to global space, and vice versa.
* Updated the Skeleton3D class reference.
* Changed the icon used for bones in the Skeleton3D inspector to use BoneAttachement3D's icon.
* Changed the Skeleton3D inspector to use EditorPropertyTransform and EditorPropertyVector3 when possible.
* Placed the Transform/Matrix for each bone in a sub-section, so it is visually similar to the Node3D inspector.

logging feature.

Fixes #32488.

GDScript LSP: Fix wrong error checks added in #39385

Add note about automatic window title to FileDialog documentation.

MSDN says:

> When you write .dds files, you should set the DDSD_CAPS and
> DDSD_PIXELFORMAT flags, and for mipmapped textures you should also
> set the DDSD_MIPMAPCOUNT flag. However, when you read a .dds file,
> you should not rely on the DDSD_CAPS, DDSD_PIXELFORMAT, and
> DDSD_MIPMAPCOUNT flags being set because some writers of such a file
> might not set these flags.
