Fix T89122: crash when multi input is connected to multiple group inputs

The early `return` was wrong when there are multiple origin sockets
that need to be loaded.

Fix T89329: icosphere subdivisions can be set to 0

Differential Revision: https://developer.blender.org/D11658

Cleanup: use doxy sections in view3d iterators

Cleanup: variable naming in view3d_iterators

Consistently use a/b instead of 0/1.

Fix T32214: Wireframe edge select fails with verts behind the view

This resolves a long standing bug in edge selection
(picking, circle, box & lasso).

Now when one of the edges vertices fails to project into screen space,
the edge is clipped by the viewport to calculate an on-screen location
that can be used instead.

This isn't default as it may be important for the on the screen location
not to be clipped by the viewport.

Cleanup: pass objects as const arguments

Cleanup: swap top/bottom args to planes_from_projmat

X & Z were ordered min/max, where as Y was max/min.

Fix T89271: Selecting all vertices doesn't select all edges.

Mistake in recent commit {rBea4309925f1d2d2a224bd1dce12269a58ade9b62}.

Cleanup: Rename spline interpolation functions

The names were slightly longer than they needed to be clear,
and when they are shorter they tend to fit on one line better.

Geometry Nodes: Multithread curve resample node

Optimize the node for the case of many splines. In a test file with
14000 splines, the node is 3x faster (72ms to 24ms) on an 8 core CPU.

Cleanup: use early return in view3d iterator callbacks

Docs: improve imbuf.write docstring

The file path wasn't documented as being optional.

Delaunay add support for detecting and removing holes from output.

Adds two new output modes to the CDT api which detect and remove
holes. A hole is a face from which a ray shot to the outside
intersects an even number of constraint edges, except we don't
count constraint edges in the same connected region of faces,
where a region is connected via non-constraint edges.

These modes are useful for filling in outlines meant to represent
text characters and the like.

Original patch was from Erik Abrahamsson, modified by me to work
with the "valid Bmesh" output type too. I also added tests
for the new modes.

Fix T89310: Industry Compatible keymap not working

Caused by improper testing on my part, assuming a helper function
existed in the industry compatible keymap file, and also assuming it
also used the N and T keys for the left and right side-regions.

Curves: Multithread Curve to CurveEval conversion

A different data structure / implementation is used for curves in the
node tree currently. Converting from the DNA `Curve` structure to this
wasn't slow, but it's nice to decrease overhead. In a test of 14000
splines with 128000 points, this halves the runtime from about 5ms
to about 2.5ms.

Fix: Spreadsheet selection filter crash on non-mesh components

The spreadsheet filter tried to apply the mesh selection filter on non-
mesh geometry components. Add a check for the component type,
and also refactor the function to be more easily readable.

Fix T89302: Broken normals after mesh to curve node

The normals were broken because the normal calculation mode wasn't set.
This patch adds a default normal mode so all code creating a spline does
not necessarily have to set it manually. In the future there should be a
way to change this value in the node tree.

Docs: improve poly_to_tri_count doc-string

It wasn't obvious this can be used for calculating the triangle index
from the polygon and loop index.

Cleanup: use eSpace_Type enum type

Cleanup: remove contents of endif() in cmake

This convention is no longer used for Blender's CMake files.
