In the unlikely case an area could not be created OPERATOR_CANCELLED
was returned, this has the same value of WM_HANDLER_HANDLED however
break is logical in this situation and both flags work.

Whenever a transform operation is activated by gizmo, the gizmo
modal is maintained, but its drawing remains the same even if the
transform mode or constrain is changed.
So update the gizmo according to the mode or constrain set.
NOTE: Currently only 3D view gizmo is affected
`WM_modalkeymap_items_to_string` is expected to always return a string.
But in the special case of zero length, the returned string was not
terminated with `'\0'`.
This can cause problems with the header of the knife tool for example.
It always uses the returned string.
(This issue was observed when investigating T103804).
Also minor changes in comments:
- Reference BLENDER_HISTORY_FILE instead of the literal file-name
(simplifies looking up usage).
- Use usernames in tags, as noted in code-style.
Regression in [0] which cleared the redo-panel if an operator added
its own undo step. This worked for sculpt to fix T101743, but caused
the redo-panel to be cleared for actions who's undo steps where created
by nested operators (which is the case for the spin operator).
Fix by checking an undo-step is added without registering an operator.

Currently only affects 'UI' IDs (WindowManager, Screen, etc.), but in
the future other types may be affected as well.
NOTE: this is only used in readfile code itself, not in the
post-processing performed by `setup_app_data`, as this code is too
specific for such generic handling.
Regression in [0] caused mouse wheel events over windows without focus
to use the modifier state at the point the window was de-activated.
Now un-focused windows have all events release, when focused again
modifier press events are set again.

Swap-buffers was being deferred (to prevent it being called
from the event handling thread) however when it was called the
OpenGL context might not be active (especially with multiple windows).
Moving the cursor between windows made eglSwapBuffers report:
EGL Error (0x300D): EGL_BAD_SURFACE.
Resolve this by removing swapBuffer calls and instead add a
GHOST_kEventWindowUpdateDecor event intended for redrawing
client-side-decoration.
Besides the warning, this results an error with LIBDECOR window frames
not redrawing when a window became inactive.
Goal of this patch is to stop the invocation of OpenGL calls via the bgl module
on a none OpenGL GPU backend, report this as a python deprecation warning
and report this to the user.
## Deprecation warning to developers
```
>>> import bgl
>>> bgl.glUseProgram(0)
<blender_console>:1: DeprecationWarning: 'bgl.glUseProgram' is deprecated and will be removed in Blender 3.7. Report or update your script to use 'gpu' module.
```
## Deprecation message to users
The message to the user is shown as part of the Info Space and as a message box.
{F14159203 width=100%}
{F14158674 width=100%}
During implementation we tried several ideas:
# Use python warning as errors: This isn't fine grained enough and can show incorrect information to the user.
# Throw deprecation as error and use sys.excepthook to report the user message.
This required a custom exception class to identify the bgl deprecation and a CPython handler function to
be set during python initialization. Although this is the most flexible there was a disconnect between the
exception class, exception function and the excepthook registration.
# A variant how we handle autoexec failures. A flag is stored in Global and when set the user message is reported.
Not that flexible, but code is more connected to the boolean stored in the Global struct.
Although using Global struct isn't nice I chose this solution due to its traceability. It is clear to developers
reading the code how the mechanism works by using search all functionality of your IDE.

These warnings can reveal errors in logic, so quiet them by checking
if the features are enabled before using variables or by assigning
empty strings in some cases.
- Check CMAKE_THREAD_LIBS_INIT is set before use as CMake docs
note that this may be left unset if it's not needed.
- Remove BOOST/OPENVDB/VULKAN references when disable.
- Define INC_SYS even when empty.
- Remove PNG_INC from freetype (not defined anywhere).
When idle, each 3D view made two calls CTX_data_mode_enum(C) from the
WM_main loop. While not causing problems it complicated troubleshooting
high CPU use while idle in other areas.
Access the object via the view layer, giving approx 40x speedup.
An apostrophe should not be used because it is not a mark of plural,
even for initialisms. This involves mostly comments, but a few UI
messages are affected as well.

Due an internal scale of the brush size done by grease pencil
draw tool (this scale factor cannot be removed), the size of the
radial control is not equal to the actual stroke thickness and
this makes the radial size displayed useless.
This patch adds a new property that allows to pass the
path of the tool path and this value is used to apply
the correct scale to the radial size.

(MacOS) only: In the System tab of the user preferences the user has the
ability to select a GPU backend that Blender will use. After changing
the GPU backend setting, the user has to restart Blender before the
setting is used.
It was added to start collecting feedback on the Metal backend without
using the command lines.
By default Blender will select OpenGL as backend. When Metal is selected
(via `--gpu-backend metal` or via user preferences) OpenGL will be used as
fallback when the platform isn't capable of running Metal.
