Drop events ignored the cursor coordinates, under the assumption that
cursor motion events would also be sent to update the cursor location.
This depended on the behavior of the compositor, it failed for Sway
but worked for Gnome-shell & River.
Resolve by making use of the drop events cursor coordinates.
Backend initialization needs to be delayed until after the OpenGL context
is created. This worked fine in foreground mode because the OpenGL context
already exists for the window at the point GPU_backend_init_once was called,
but not for background mode.
Create the backend just in time in GPU_context_create as before, and
automatically free it when the last context id discarded. But check if any
GPU backend is supported before creating the OpenGL context.
Ref D15463, D15465
This causes an assert with libepoxy, but was wrong already regardless.
Refactor logic to work as follows:
* GPU_exit() deletes backend resources
* Destroy UI GPU resources with the context active
* Call GPU_backend_exit() after deleting the context

When rendering with headless builds, show an error instead of crashing.
Previously GPU_backend_init was called indirectly from
DRW_opengl_context_create, a new function is now called from the window
manager (GPU_backend_init_once), so it's possible to check if the GPU
has a back-end.
This also disables the `bgl` Python module when building WITH_HEADLESS.

The goal of this change is to fix an increasing bottleneck of the event
queue handling when there is an operator bound to a key press event and
is taking longer to finish than a key-repeat speed on the system.
Practical example of when it happens is the marker tracking operator in
a single-frame track mode. Quite often artists will hold down Alt-arrow
to track a segment of footage which seems trivial to track. The issue
arises when the Alt-arrow is released: prior to this change it is was
possible that more frames will be tracked. It also seems that redraws
are less smooth.
It is a bit hard to make easily shareable computer-independent test
case. Instead, a synthetic case can be reproduced by adding a 50 ms
sleep in the `text_move_exec()`. In such synthetic case open a long
text in the text editor and hold left/right arrow button to navigate
the cursor. The observed behavior is that seemingly redraws happen
less and less often and cursor travels longer and longer distances
between redraws. The cursor will also keep moving after the buttons
has been released.
The proposed solution is to ignore sequential key-press events from
being added to the event queue. This seems to be the least intrusive
and the most safe approach:
- If the operator is fast enough there will be no multiple press events
in the queue in both prior and after of this change.
- If the operator is slow enough, clicking the button multiple times
(i.e. clicking arrow button 3 times in a heavy shot will change the
scene frame by exactly 3 frames because no events are ignored in
this case).
- Only do it for key press events, keeping mouse and tabled behavior
unchanged which is crucial for the paint mode.
Note that this is a bit different from the key repeat tracking and
filtering which is already implemented for keymaps as here we only want
to avoid the event queue build-up and do want to ignore all repeat
events. In other words: we do want to handle as many key presses as the
operator performance allows it without clogging anything.
A possible extension to this change could be a key press counter, so
that instead of ignoring the event we merge it into the last event in
the queue, incrementing some counter. This way if some operator really
needs to know exact number of key repeats it can still access it.

We would first invoke the dragging, and then set the drag data (like the
ID or the dragged modifier), so the `wmDropBox.on_drag_start()` handler
wouldn't be able to access this. This broke dragging some IDs from the
Outliner, noticed in D15333.
It's now possible to first create/request drag data, extend it, and then
invoke the actual dragging. The normal function to start dragging
returns `void` now instead of `wmDrag *`, so the drag data can't easily
be modified after starting anymore.
- Remove references to `ISTEXTINPUT` as any keyboard event with it's
utf8_buf set can be handled as text input.
- Update references to the key repeat flag.
The `ascii` member was only kept for historic reason as some platforms
didn't support utf8 when it was first introduced.
Remove the `ascii` struct members since many checks used this as a
fall-back for utf8_buf not being set which isn't needed.
There are a few cases where it's convenient to access the ASCII value
of an event (or nil) so a function has been added to do that.
*Details*
- WM_event_utf8_to_ascii() has been added for the few cases an events
ASCII value needs to be accessed, this just avoids having to do
multi-byte character checks in-line.
- RNA Event.ascii remains, using utf8_buf[0] for single byte characters.
- GHOST_TEventKeyData.ascii has been removed.
- To avoid regressions non-ASCII Latin1 characters from GHOST are
converted into multi-byte UTF8, when building X11 without
XInput & X_HAVE_UTF8_STRING it seems like could still occur.
Some ID types did not have a filter value, even though they would be
used in remapping code, leading to missing remappings. In that specific
case, shape keys would actually never be properly remapped.

This is a good indicator to have and such workspace-wide functionality should

Downside is that it makes this already crowded region even more crowded. But

Adds a "Pin Scene" option to the workspace. When activated, the workspace will
remember the scene that was last activated in it, so that when switching back
to this workspace, the same scene will be reactivated. This is important for a
VSE workflow, so that users can switch between different workspaces displaying
a scene and thus a timeline for a specific task.
The option can be found in the Properties, Workspace tab. D11890 additionally
adds an icon for this to the scene switcher in the topbar.
The workspace data contains a pointer to the scene which is a UI to scene data

Use client (window) relative coordinates for cursor position access,
this only moves the conversion from window-manager into GHOST,
(no functional changes).
This is needed for fix a bug in GHOST/Wayland which doesn't support
accessing absolute cursor coordinates & the window is needed to properly
access the cursor coordinates.
As it happens every caller to GHOST_GetCursorPosition was already making
the values window-relative, so there is little benefit in attempting to
workaround the problem on the Wayland side.
If needed the screen-space versions of functions can be exposed again.
MTLFrameBuffer has been implemented to support creation of RenderCommandEncoders, along with supporting functionality in the Metal Context.
Optimisation stubs for GPU_framebuffer_bind_ext has been added, which enables specific assignment of attachment load-store ops at the bind level, rather than on a framebuffer object as a whole.
Begin and end frame markers are used to encapsulate frame boundaries for explicit workload submission. This is required for explicit APIs where implicit flushing of work does not occur.

Fix by always testing unhandled double-click events as press events,
irrespective of the previous event type.
**Details**
Handling double-click events only ran when the previously pressed-key
matched the current pressed-key.
Originally when double-click support was added the previous type was
compared (ignoring it's press/release value) and while not necessary
it was harmless as it matched the check for double-click events being
generated.
As of [0] the logic for click/drag detection changed to ignore release
events as release this could interrupt dragging.
This made it possible to generate double-click events that failed the
`event->prev_press_type == event->type` comparison.
In these cases it was possible to generate double-click
events that would not fall-back to a 'press' value when unhandled.

Add a method to access the custom cursor from GHOST which is used
for drawing a software cursor. This means the knife tools cursor now
work as expected.
Although non-custom cursors are still not supported.
The current gnome-shell (v42.2) has a bug where grabbing the cursor
doesn't scale the region when confining it to the window.
For Hi-DPI displays this means the cursor may be confined to a quarter
of the window, making grab unusable.
Even though this has been fixed up-stream the issue remains in the
latest release - so workaround the problem by implementing window
confined grab using a software cursor.
This is only used gnome-shell for displays that use Hi-DPI scaling.
Allow use of multiple fonts acting together like a fallback stack,
where if a glyph is not found in one it can be retrieved from another.

The software cursor was being enabled with absolute events,

at the location used by Blender.
Without this, the cursor was locked at the location where grab started,
making some actions unusable since the cursor location was invisible.
Resolves T77311.
NOTE: this patch originated in T98015 which was split into multiple
reports. While it could be split into multiple patches these are very
much related so keeping as one for now
This patch fixes the following issues:
[1] autokeying transforms in preview only creates keyframes if there is
an FCurve already
[2] autokeying transforms in preview only creates keyframes for
rotation/scale if rotating/scaling around cursor (should keyframe
position as well)
[3] autokeying transforms in preview does not work during animation
playback
For [1], a param was added to `ED_autokeyframe_property` which can tweak
its default behavior of only creating keyframes on already keyed
properties (which was fine because this is mostly called from buttons
where this behavior is desired). Callers such as gizmos (or the VSE in
our case) can use this additional param so that keyframes are also
created on "not-yet-keyframed" properties.
For [2], the pivot is checked and position properties also keyed if
necessary (which is also consistent with the way objects are keyed in
the 3DView)
For [3], `animrecord_check_state` was changed to be able to work on
scenes as well and the transform system in the VSE preview was made
aware of the screen's `animtimer`.
NOTE: there are still things to be improved for keyframing in the VSE,
the most obvious is probably a `keyframe_insert` operator (with
keyingsets)

The transformation snapping code contains a bunch of `#define`s, some ambiguously or incorrectly named attributes. This patch contains refactored code to improve this. This patch does (should) not change functionality of snapping.
Clarified ambiguously / incorrectly named attributes.
- "Target" is used to refer to the part of the source that is to be snapped (Active, Median, Center, Closest), but several other areas of Blender use the term "target" to refer to the thing being snapped to and "source" to refer to the thing getting snapped. Moreover, the implications of the previous terms do not match the descriptions. For example: `SCE_SNAP_TARGET_CENTER` does not snap the grabbed geometry to the center of the target, but instead "Snap transforamtion center onto target".
- "Select" refers to the condition for an object to be a possible target for snapping.
- `SCE_SNAP_MODE_FACE` is renamed to `SCE_SNAP_MODE_FACE_RAYCAST` to better describe its affect and to make way for other face snapping methods (ex: nearest).
Refactored related `#define` into `enum`s. In particular, constants relating to...
- `ToolSettings.snap_flag` are now in `enum eSnapFlag`
- `ToolSettings.snap_mode` are now in `enum eSnapMode`
- `ToolSettings.snap_source` (was `snap_target`) are now in `enum eSnapSourceSelect`
- `ToolSettings.snap_flag` (`SCE_SNAP_NO_SELF`) and `TransSnap.target_select` are now in `enum eSnapTargetSelect`
As the terms became more consistent and the constants were packed together into meaningful enumerations, some of the attribute names seemed ambiguous. For example, it is unclear whether `SnapObjectParams.snap_select` referred to the target or the source. This patch also adds a small amount of clarity.
This patch also swaps out generic types (ex: `char`, `short`, `ushort`) and unclear hard coded numbers (ex: `0`) used with snap-related enumerations with the actual `enum`s and values.
Note: I did leave myself some comments to follow-up with further refactoring. Specifically, using "target" and "source" consistently will mean the Python API will need to change (ex: `ToolSettings.snap_target` is not `ToolSettings.snap_source`). If the API is going to change, it would be good to make sure that the used terms are descriptive enough. For example, `bpy.ops.transform.translate` uses a `snap` argument to determine if snapping should be enabled while transforming. Perhaps `use_snap` might be an improvement that's more consistent with other conventions.
This patch is (mostly) a subset of D14591, as suggested by @mano-wii.
Task T69342 proposes to separate the `Absolute Grid Snap` option out from `Increment` snapping method into its own method. Also, there might be reason to create additional snapping methods or options. (Indeed, D14591 heads in this direction). This patch can work along with these suggestions, as this patch is trying to clarify the snapping code and to prompt more work in this area.
