FLT_EPSILON was added to the threshold when comparing values,
this caused problems selecting similar small faces since the areas
can be very small in this case.
Also increase the displayed precision so it's easier to use
smaller numbers.
Selecting random percentage would not reliably guarantee the precise
percentage of selected elements now randomize an index array instead
and use the precise number of elements from this array.
Note that this change has only been made to edit-mesh
and should be applied to all random selection operators.
- Don't use `r_` prefix for an argument that's also read from
(this is meant for return only arguments).
- Rename variables to make it clear the distance is pixels,
using manhattan length measurement.
Regression in 80cbbd2843.
Unfortunately keeping selection picking behavior as well as
supporting finding the nearest face within a radius requires an
inconsistency between x-ray and back-buffer selection that
doesn't work well using the current arguments.
Resolve by adding an argument that causes the input distance
to be ignored for back-buffer selection.
This is used by selection picking but not the knife tool.
This changes behavior for path-selection in face mode,
which now uses a margin for back-buffer selection.
From my own testing this doesn't seem to be a problem like it could be
for regular selection picking.
Minor changes preparing for snap gizmo inclusion.
- Extract `knife_snap_edge_in_angle` into a utility function.
- Check the snap vertex on closest edge instead of the face.
- Add MODE_INVOKING state.
- Remove unnecessary NULL checks.
- Control 'ignore_edge_snapping' while dragging instead of checking
dragging in `knife_snap_update_from_mval`.

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.
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.
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.
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.
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.
- comment added in struct `KnifeTool_OpData`
- struct pointer name `lst` updated to `list` ( Guess its more readable )
- `KNF_MODEL_IGNORE_SNAP_ON` updated to `KNF_MODAL_IGNORE_SNAP_ON`
- `KNF_MODEL_IGNORE_SNAP_OFF` updated to `KNF_MODAL_IGNORE_SNAP_OFF`

Warnings in tooltips were using inconsistent formatting, some in
parantheses, some not, some in caps, others not, some on new lines,
some not, etc.
This patch uses a consistent new line and no capitals for these cases.

This adds the LineArt grease pencil modifier.
It takes objects or collections as input and generates various grease
pencil lines from these objects with the help of the active scene
camera. For example it can generate contour lines, intersection lines
and crease lines to name a few.
This is really useful as artists can then use 3D meshes to automatically
generate grease pencil lines for characters, enviroments or other
visualization purposes.
These lines can then be baked and edited as regular grease pencil lines.

Changes to increase subdivision by one along both axis (X and Y)
For example with x_segment = 3 and y_segment = 3.
There should be 16 vertices ((3 + 1) * (3 + 1)) for correct
number of subdivisions. Currently they are 3 * 3 = 9 vertices.

The Tool stores desired dimensions as `scale` and thus had to half the
scale again in `make_prim_init()` because by default all primitives are
created at a size of 2 in blender.
This worked, but:
- [1] it logged something like size=2, scale=2,2,2 for a 2x2x2 cube
[which does not sound right, it should be size=2 scale=1,1,1]
- [2] it had to make an exception for the case scale is exactly 1x1x1
[this happens when the property is not set specifically, e.g. adding
primitives from the menu]
-- this exception led to double sized primitives being created when the
tool asked for exact dimensions of 1x1x1
Now - instead of compensating in `make_prim_init()` - do this earlier in
the tool itself, see `view3d_interactive_add_modal`, this fixes the bug
and now also correctly logs size=2 scale 0.5,0.5,0.5 for a 1x1x1 cube.

The commit rB6f63417b500d that made exact boolean work on meshes
with holes (like Suzanne) unfortunately dramatically slowed things
down on other non-manifold meshes that don't have holes and didn't
need the per-triangle insideness test.
This adds a hole_tolerant parameter, false by default, that the user
can enable to get good results on non-manifold meshes with holes.
Using false for this parameter speeds up the time from 90 seconds
to 10 seconds on an example with 1.2M triangles.
Move some drawing code from `area.c` and `ed_util.c` into `ed_draw.c`.
This is to support the new generic slider that wil be used in T81785.
No functional changes.

In vertex selection mode, the "At First" and "At Last" options are
contextually added to the beginning of the list of merge operations.
This means the automatic shortcuts in the merge menu are different,
making learning the shortcuts much more difficult than necessary.
This patch reorders the items so that "At First" and "At Last" are
added after the first three options so the shortcuts are always
consistent.

The inset operator would display the inset thickness and depth as
Blender units during transform. This meant that when the scene units
were set to something different than meters, the display value would
give different results than entering the same number using the value
input. (Similar to D10325)
The fix makes sure that the numbers are always displayed in the correct
scene units.
