* Clean-up of node_3d_editor_plugin.{h,cpp}: removed unused code, fixed some bugs.
* Moved node_3d_editor_gizmos.{h,cpp} to editor/plugins.
* Added support for multiple gizmos per node. This means custom gizmos will no longer override the built-in ones and that multiple gizmos can be used in more complex nodes.
* Added support for handle IDs. When adding handles to a gizmo, an ID can be specified for each one, making it easier to work with gizmos that have a variable number of handles.
* Added support for subgizmos, selectable elements that can be transformed without needing a node of their own. By overriding _subgizmo_intersect_frustum() and/or _subgizmo_intersect_ray() gizmos can define which subgizmos should be selected on a region or click selection. Subgizmo transformations are applied using get/set/commit virtual methods, similar to how handles work.
The internal processing code only works for OS windows, since it takes
the mouse position relative to the window and not the viewport. Now we
make sure it's not called in single-window mode.
This pull request fixes an assortment of typos and improves conciseness in `Animation`, `Area2D`, `Array`, `ArrayMesh`, `Control`, `Directory`, `EditorPlugin`, `Engine`, and `OS`.
`localhost` was removed as it won't work out of the box. It can be added
by the user if they're working on the asset library itself.
This won't affect existing installations due to how the editor settings
are stored, but existing installations will keep working fine.
The various get_meta, set_meta, has_meta, get_meta_list, remove_meta
functions now uses StringName, allowing further optimizations via the
SNAME macro when used from C++ (this PR does not change the various
usage though).
* Friendlier with version control.
* Generates pseudo unique IDs, to minimize conflicts when merging, but still
user readable (so, not UUID).
* Eventually will also allow to have more precisely named sub-resources in
imported files.
* This will allow better reloading on changes (including resources already
loaded) as well as better keeping track of changes on the DCC.
* Keeps backward compatibility with the old formats.
* Binary and text format version incremented to mark breakage in forward
compatibility.
When a popup is going to be closed, switch focus to the parent only if
the popup is still being focused.
Fixes some cases with specific WMs where due to the order of events, a
new popup could be immediately unfocused because a previously opened
and closed popup is switching focus to the parent.
The member popped_up is used to avoid closing a Popup before it had a
chance to be focused. It wasn't reset properly when the popup is hidden,
causing the Popup to close right after showing in some random cases
(spotted on X11, might not happen on Windows).
