ea93e5df6c Asset: Merge asset library/list refresh operators
In rBdcdbaf89bd11, I introduced a new operator
(`file.asset_library_refresh()`) to handle Asset Browser refreshing more
separate from File Browser refreshing. However, there already was
`asset.asset_list_refresh()`, which at this point only works for asset
view templates, but was intended to cover the Asset Browser case in
future too. This would happen once the Asset Browser uses the asset list
design of the asset view template.

So rather than having two operators for refreshing asset library data,
have one that just handles both cases, until they converge into one.
This avoids changes to the Python API in future (deprecating/changing
operators).

dcdbaf89bd Asset Browser: Correct name & tooltip for asset list refresh operator
The name and tooltip were talking about file-lists, which exposes the
fact that the Asset Browser uses the File Browser code in the UI, which
we shouldn't do. This can confuse users.
Instead have a dedicated operator for the Asset Browser with a proper
name and tooltip.

ca2ae350ec Asset Browser: Improve hint for asset library that isn't found
We already show a message when showing an asset library whose path can't be
found on disk. The red text was making it look like some fatal error happened.
And the message could be a bit more useful generally.

So this removes the red color of the text, (arguably) improves the text and
adds a button as shortcut to open the Preferences with the asset library
settings.

3391a2ef1d Assets: Show all assets indirectly nested inside the active catalog
The asset catalog design was always that the active catalog would also
display all assets of its child catalogs (or grand-childs, etc.). This
is one of the main characteristics that differentiates catalogs from
usual directories.

Sybren prepared this on the asset catalog backend side with
56ce51d1f7. This integrates it into the Asset Browser backend and the
UI.

c4dca65228 Asset Browser: Support dragging assets into catalogs
With this it is possible to select any number of assets in the Asset
Browser and drag them into catalogs. The assets will be moved to that
catalog then. However, this will only work in the "Current File" asset
library, since that is the only library that allows changing assets,
which is what's done here.

While dragging assets over the tree row, a tooltip is shown explaining
what's going to happen.

In preparation to this, the new UI tree-view API was already extended
with custom drop support, see 4ee2d9df42.

----

Changes here to the `wmDrag` code were needed to support dragging multiple
assets. Some of it is considered temporary because a) a proper #AssetHandle
design should replace some ugly parts of this patch and b) the multi-item
support in `wmDrag` isn't that great yet. The entire API will have to be
written anyway (see D4071).

9d9f205dc4 Asset Browser: Initial Asset Catalog UI
The Asset Browser now displays a tree with asset catalogs in the left
sidebar.
This replaces the asset categories. It uses the new UI tree-view API
(https://wiki.blender.org/wiki/Source/Interface/Views#Tree-View).
Buttons are displayed for adding and removing of catalogs. Parent items
can be collapsed, but the collapsed/uncollapsed state is not stored in
files yet.
Note that edits to catalogs (e.g. new or removed catalogs) are only
written to the asset library's catalog definition files when saving a
.blend.

In the "Current File" asset library, we try to show asset catalogs from
a parent asset library, or if that fails, from the directory the file is
stored in. See adaf4f56e1.

There are plenty of TODOs and smaller glitches to be fixed still. Plus a
UI polishing pass should be done.

Important missing UI features:
* Dragging assets into catalogs (WIP, close to being ready).
* Renaming catalogs
* Proper handling of catalogs in the "Current File" asset library
  (currently not working well).

The "Current File" asset library is especially limited still. Since this
is the only place where you can assign assets to a catalog, this makes
the catalogs very cumbersome in general. To assign an asset to a
catalog, one has to manually copy the Catalog ID (a random hash like
number) to the asset metadata through a temporary UI in the Asset
Browser Sidebar. These limitations should be addressed over the next few
days, they are high priority.

6b0869039a File Browser: Select files and directories after renaming
(Note: This is an alternative version for D9994 by @Schiette. The commit
message is based on his description.)

Currently, when a new directory is created it is not selected.
Similarly, when renaming an existing file or directory, it does not
remain active/highlighted blue after renaming.

This change makes sure the file or directory is always selected after
renaming, even if the renaming failed or was cancelled.
This has some usability advantages:
 - Open the newly created directory without having to select it (ENTER).
 - If you make a naming mistake, you can immediately fix that (F2)
   without having to click it again.
 - If you create a directory and forget to name it, you can fix that
   (F2) without having to select it.
 - This is consistent with many common File Browsers.

Further, selecting the item even after renaming failed or was cancelled
helps keeping the file in focus, so the user doesn't have to look for it
(especially if the renaming just failed which the user may not notice).
In other words, it avoids disorienting the user.

Also see D11119 which requires this behavior.

We could also always select the file/directory on mouse press. This
would make some hacks unnecessary, but may have further implications. I
think eventually that's what we should do though.

6c8c30d865 Fix T82002: ENTER does nothing when mouse cursor is over save dialog text field
The `file.execute` operator would early-exit because the mouse wasn't hovering
the file list. Caused by 4ba9d7d71e.

Although simpler solutions would have been possible, I decided it's better to
split add a new operator for executing based on the mouse (for double-clicking
files), to separate that from the window level execute operator
(`file.execute`). This allows more control and we can get rid of the implicit
assumption that the keymap would call `file.select` on mouse-press, and
`file.execute` on double-click, for the double-click behavior to work. The cost
is that we execute the file selection & activation logic twice on the
double-click, but that shouldn't be an issue at all.
Also removes the `need_active` property from the `file.execute` operator.
That's ancient and wasn't implemented well anyway.

To be clear, reason this fixes the bug is that `file.execute` works entirely
with the `execute()` callback now and doesn't early-exit based on the mouse
position anymore.

Might trigger warnings about the `need_active` property not being found for
custom keymaps. These can be ignored and the property can safely be removed
from the keymap. I don't expect other keymap breakages.

5a67407d5a File Browser: scroll selected files into view
Add operator `FILE_OT_view_selected` to the file browser (and thus also
to the asset browser) that scrolls selected files into view.

This includes the active file, even though it is not selected. In
certain cases the active file can loose its selected state (clicking
next to it, or refreshing the asset browser), but then it's still shown
in the right-hand sidebar. Because of this, I found it important to take
it into account when scrolling.

This also includes a change to the keymaps:
- Blender default: {key NUMPAD_PERIOD} is removed from the "reload"
  operator, and assigned to the new "view selected files" operator. The
  reload operator was already doubly bound, and now {key R} is the only
  remaining hotkey for it.
- Industry compatible: {key F} is assigned to the new "view selected
  files" operator. This is consistent with the other "view selected"
  operators in other editors.

Add an RNA function `activate_asset_by_id(asset_id: ID, deferred: bool)`
to the File Browser space type, which intended to be used to activate an
asset's entry as identified by its `ID *`. Calling it changes the active
asset, but only if the given ID can actually be found.

The activation can be deferred (by passing `deferred=True`) until the
next refresh operation has finished. This is necessary when an asset has
just been added, as it will be loaded by the filebrowser in a background
job.

2d6a69ae4e Asset System: New Asset Browser editor
This introduces the User Interface part of the Asset Browser, based on the
design in T54642.

Additions:
* New Asset Browser (internally a sub-editor of the File Browser).
* Navigation region showing asset categories.
* Main region showing the assets of the selected asset library with previews.
  The assets may be stored over multiple .blends in the directory that's
  "mounted" as asset library in the Preferences. They will all be shown in this
  list.
* Header with an asset library dropdown, allowing to choose the active asset
  library to show. Options are the "Current File" as asset library and all
  custom libraries.
* Display popover, filter popover and search box (partially dummies, see
  T82680).
* Sidebar showing the metadata of the currently active file (name, preview,
  description and tags), which can be edited for assets in the "Current File"
  asset library. (For others it will reset on reload.)
* The sidebar includes a button to load a custom preview image from a file.
* Make asset files draggable (with preview image).
* If a library with invalid path is selected, a message is drawn in the main
  region to help the user understand what's wrong.
* Operators to add and remove asset tags. Exposed in the sidebar.
* "Only Assets" option for Link/Append.
* Internal utilities for asset UI scripts.

For screenshots or demo videos, please see D9725. Or the 2.92 release notes.

Note that there are many things to be tweaked and polished in the Asset Browser
UI still. For example, the filter and display popovers are mostly dummies. See
T82680.

**File-Lists**
* Support loading assets with metadata read from external files into the
  file-list.
* New main based file-list type, for the "Current File" asset library.
* Refresh file-list when switching between browse modes or asset libraries.
* Support empty file-lists (asset library with no assets).
* Store file previews as icons, so scripts can reference them via icon-id. See
  previous commit.

**Space Data**
* Introduce "browse mode" to differeniate between file and asset browsing.
* Add `FileAssetSelectParams` to `SpaceFile`, with `FileSelectParams` as base.
  Makes sure data is separated between asset and file browsing when switching
  between them. The active params can be obtained through
  `ED_fileselect_get_active_params()`.
* `FileAssetSelectParams` stores the currently visible asset library ID.
* Introduce file history abstraction so file and asset browsing can keep a
  separate history (previous and next directories).

**General**
* Option to only show asset data-blocks while file browsing (not exposed here).
* Add "active_file" context member, so scripts can get and display info about
  the active file.
* Add "active_id" context member, so `ED_OT_lib_id_load_custom_preview` can set
  a custom ID preview. (Only for "Current File" asset library)
* Expose some of `FileDirEntry` in RNA as (non-editable). That way scripts can
  obtain name, preview icon and asset-data.

region in case it's not there. Now we should be able to savely assume
the tool region to be there, whithout any unusual lazy-creation.

This makes it so that regions only needed when the file browser is
invoked as an operation (e.g. Ctrl+O rather than a regular editor) are
lazy created then, and removed if the file browser is changed into a

Cancel).

That should remove some troublesome assumptions and makes versioning
redundant.

cancelling a file operation invoked from a regular file browser editor.

ee8f69c96c UI: File Browser Design Overhaul
This is a general redesign of the File Browser GUI and interaction
methods. For screenshots, check patch D5601.

Main changes in short:
* File Browser as floating window
* New layout of regions
* Popovers for view and filter options
* Vertical list view with interactive column header
* New and updated icons
* Keymap consistency fixes
* Many tweaks and fixes to the drawing of views

----

General:
* The file browser now opens as temporary floating window. It closes on
  Esc. The header is hidden then.
* When the file browser is opened as regular editor, the header remains
  visible.
* All file browser regions are now defined in Python (the button
  layout).
* Adjusted related operator UI names.

Keymap:
Keymap is now consistent with other list-based views in Blender, such as
the Outliner.
* Left click to select, double-click to open
* Right-click context menus
* Shift-click to fill selection
* Ctrl-click to extend selection

Operator options:
These previously overlapped with the source list, which caused numerous
issues with resizing and presenting many settings in a small panel area.
It was also generally inconsistent with Blender.
* Moved to new sidebar, which can easily be shown or hidden using a
  prominent Options toggle.
* IO operators have new layouts to match this new sidebar, using
  sub-panels. This will have to be committed separately (Add-on
  repository).
* If operators want to show the options by default, they have the option
  to do so (see `WM_FILESEL_SHOW_PROPS`, `hide_props_region`), otherwise
  they are hidden by default.

General Layout:
The layout has been changed to be simpler, more standard, and fits
better in with Blender 2.8.
* More conventional layout (file path at top, file name at the bottom,
  execute/cancel buttons in bottom right).
* Use of popovers to group controls, and allow for more descriptive
  naming.
* Search box is always live now, just like Outliner.

Views:
* Date Modified column combines both date and time, also uses user
  friendly strings for recent dates (i.e. "Yesterday", "Today").
* Details columns (file size, modification date/time) are now toggleable
  for all display types, they are not hardcoded per display type.
* File sizes now show as B, KB, MB, ... rather than B, KiB, MiB, … They
  are now also calculated using base 10 of course.
* Option to sort in inverse order.

Vertical List View:
* This view now used a much simpler single vertical list with columns
  for information.
* Users can click on the headers of these columns to order by that
  category, and click again to reverse the ordering.

Icons:
* Updated icons by Jendrzych, with better centering.
* Files and folders have new icons in Icon view.
* Both files and folders have reworked superimposed icons that show
  users the file/folder type.
* 3D file documents correctly use the 3d file icon, which was unused
  previously.
* Workspaces now show their icon on Link/Append - also when listed in
  the Outliner.

Minor Python-API breakage:
* `bpy.types.FileSelectParams.display_type`: `LIST_SHORT` and
  `LIST_LONG` are replaced by `LIST_VERTICAL` and `LIST_HORIZONTAL`.

Removes the feature where directories would automatically be created if
they are entered into the file path text button, but don't exist. We
were not sure if users use it enough to keep it. We can definitely bring
it back.

f69e9681fa Final 'FileBrowser First Stage' merge.
It basically rewrites most of filelist.c, with some more limited changes in other areas of filebrowser.

From user perspective, it:
* Removes some info in 'long' drawing mode (owner, permissions) - OS-specific data that do not really matter in Blender!
* Makes short/long display 'fixed' size (among four choices, like thumbnails mode).
* Allows to list several layers of dirtree at once, in a flat way (inside .blend files and/or real directories).
* Consequently, adds datablocks types filtering.
* Uses way less RAM when listing big directories, especially in thumbnail mode (we are talking of several hundred of MiB spared).
* Generates thumbnails way faster.

From code perspective, it:
* Is ready for asset engine needs (on data structure level in filebrowser's listing).
* Simplifies and makes 'generic' file listing much lighter.
* Separates file listing in three different aspects:
** 'generic' filelisting (in BLI), which becomes a shallow wrapper around stat struct.
** 'filebrowser drawing' filelisting, which only contains current visible subset of the whole list (sliding window), with extra drawing data (strings for size, date/time, preview, etc.).
** 'asset-ready' filelisting, which is used for operations common to 'basic' filehandling and future asset-related one.
* Uses uuid's to handle file selection/state in the browser, instead of using flags in filelisting items.
* Uses much lighter BLI_task handling for previews, instead of heavy 'job' system (using the new 'notifier' timer to handle UI refresh, in similar way to jobs).
* Moves .blend datablocks preview handling to IMB_thumbnail (necessary to avoid storing all datablock previews at once, and gives better consistency and performances too).

* Last selected file/directory is opened now (in sync with upper text-buttons)
* Changes text in open button to "Open Directory" if a directory is selected

939948c233 File Browser Arrow Keys Navigation
Adds support for selecting/deselecting files in File Browser using the
arrow keys. All directions (up, down, left, right) are possible.

When to Select, When to Deselect?
Standard behaviour is selecting, however if we move into a block of
already selected files (meaning 2+ files are selected) we start
deselecting

Possible Selection Methods
Simple selection (arrow-key): All other files are deselected
Expand selection (Shift+arrow key): Add to/remove from existing
selection
ill-Expand selection (Ctrl+Shift+arrow key): Add to/remove from existing
selection and fill everything in-between

From which file do we start navigating?
From each available selection method (Mouse-, Walk-, All-, Border
Select), we use the last selected file. If there's no selection at all
we use the first (down/right arrow) or last (up/left arrow) file.
(Ideally, the view would automatically be set to the new selection, but
this behaviour overlaps with an other patch I've been working on, so
prefer to do that separately)

(Also tweaks color for highlighted file for better feedback)

cc81b58277 Cleanup: deduplicate code.
FileBrowser had its own 'shorten_string' func, when we have a full fledge one in interface_widget code...
