Fix T86876: cannot modify float properties of geometry nodes modifier from Python

Previously, the code expected the id property to have the `IDP_FLOAT` type.
However, when assigning a Python float (which is a double internally)
to an id property, it would change the type to `IDP_DOUBLE`.
The fix is to allow both types in the geometry nodes modifier.

Fix T86966: crash when rendering with geometry nodes

UI hints should only be modified when the depsgraph is active.
Otherwise two threads evaluating the same object in different depsgraphs
can conflict with each other.

Overrides: Make Experimental API Fail On Usage.

It used to give a warning so test cases couldn't fail. This has been
changed in the test case so we could use an error here.

Overrides: API to create an override template.

This is functionality that isn't accessible via the user interface. The
API allows the creation and modification of an override template that
holds rules that needs to be checked when overriding the asset.

The API is setup that it cannot be changed after creation. Later on when
the system is more mature we will allow changing overrides operations.

NOTE: This is an experimental feature and should not be used in productions.

Fix T86972: transform node transforms shape keys

Comments: improve docstring for ED_view3d_clipping_test

The meaning of the return value wasn't obvious.

Cleanup: Remove unused node.c.

Was wrongly added back with the anti aliasing node patch.

Fix vert/edge knife snapping when the cursor wasn't over a face

In this case, the cage location was left zeroed which was then
projected back onto the screen to find the nearest screen space
edge/vertex.

This made snapping to the vertex/edge fail in some corner-cases
where it was intended to work.

Knife: scale points & snapping threshold by the DPI factor

The points were too small on hi-dpi displays.

Cleanup: logical error in path select picking

Resolve logical error in edbm_shortest_path_pick_invoke
where any discrepancy between EDBM_unified_findnearest and
edbm_elem_find_nearest caused the active-object to be cleared.

While it's not a problem at the moment, using a larger threshold
for path picking exposes the error.

Knife: support vert/edge snapping when not directly over a face

Respect the distance argument to EDBM_face_find_nearest,
when zero, sample a single pixel, otherwise sample a region.

Knife uses the selection-buffer to pick a face when the ray-cast failed.
This was meant to allow snapping to nearby faces however as the margin
was ignored, it was only used in edge cases where the ray-cast missed
but the pixel didn't.

Now the face-picking threshold is working as expected.

Note that other callers to EDBM_face_find_nearest have been updated
so set their distance argument to zero so this only impacts the knife.
Regular selection and path select could be modified separately if users
prefer this behavior.

Cleanup: use pragma once.

Cleanup: Add namespace to compositor.

Cleanup: Add `override` Keyword.

Compositor: Add Anti-Aliasing node

This is an implementation of Enhanced Subpixel Morphological Antialiasing (SMAA)

The algorithm was proposed by:
Jorge Jimenez, Jose I. Echevarria, Tiago Sousa, Diego Gutierrez

This node provides only SMAA 1x mode, so the operation will be done with no spatial
multisampling nor temporal supersampling. See Patch for comparisons.

The existing AA operation seems to be used only for binary images by some other nodes.
Using SMAA for binary images needs no important parameter such as "threshold", so we
perhaps can switch the operation to SMAA, though that changes existing behavior.

Notes:
1. The program code assumes the screen coordinates are DirectX style that the
vertical direction is upside-down, so "top" and "bottom" actually represent bottom
and top, respectively.

Thanks for Habib Gahbiche (zazizizou) to polish and finalize this patch.

Knife: reduce redundant face picking queries

Reduce the maximum number of queries to find the face under the
mouse cursor from 6x to 2x on cursor motion.

Calculating the screen-space detail could perform 2x look-ups
which have already been calculated.

Fix T83391: Knife sometimes snaps to object center

Knife snapping logic assumed having a face under the cursor meant
the projected positions were set.

This is not always the case as failure to ray-cast uses the back-buffer
as a fallback.

Cleanup: use parentheses in macro

Cleanup: deduplicate attribute creating code

Fix T86060: Texture Paint clone tool misleading texture UI

For projection painting tools besides the `DRAW` tool:

- Don't show the texture from viewport stencil drawing.
- Don't show the texture panel.
