* Switched QHull and GoogleTest to use FetchContent to populate their files at configure time. This means that the open3d_build_3rdparty_library function doesn't need to mark source files as generated which was causing them to be removed when running the clean target.
* Switched ImGUI to use FetchContent instead of external project so files are provided at configure time instead of build time.
* Removed vestigial ext_imgui target that used to download the imgui sources. Sources are now downloaded at configure time.

…l-org#6725) (isl-org#6733)

- Make points removable by correctly forwarding the key modifier to the already implemented function
- Fix bounding box calculation for picked point size selection (manual bbox extend calculation was wrong)
- Fix crash occurring when trying to make selection and non-pickable geometries where in scene
- Fix copy&paste error in help text for MACOS

KDTreeFlann::SetRawData had some confusion around data, data_, and
data_interface_. As a result, the data from the parameter was copied to
the member std::vector, but the interface (which takes an Eigen::Map)
used the data passed as an argument to the method.
As a result, the searches risked to be run on a dangling pointer,
instead of the intended internal storage.

However, rather than adjusting the pointer for Eigen::Map, I preferred
simplifying the code, and copy the argument to an Eigen::MatrixXd.

- ToString() for Material and string representation in Python.
- MaterialRecord to Material conversion - allows converting triangle mesh models to a map of tmeshes, including materials. Limitation: Only one material per tmesh (same as TriangleMeshModel)
- Support for emissive color reading in FileASSIMP (model) and writing for tmesh (tio FIleASSIMP)

New pre-release devel-main will be continuously updated with the devel packages for the main branch.
Also publish devel versions of viewer app.
This is to reduce Google cloud cost.

- Use file signatures (beginning bytes) instead of filename extension (png/jpg) to select decoder. jpg files with png extension and vice versa are read correctly.
- Catch libjpeg errors and report as normal Open3D exceptions. Change Open3D warnings to errors (exceptions) on jpeg I/O error.
- Simplify demo_scene example
- Clear image on read error
- Fix for github release macOS bug.

…foldEdges in t::geometry::TriangleMesh (isl-org#6657)

Split the logic from ComputeSurfaceArea into a helper static function
and introduce a new method which computes triangle areas and writes the
resulting tensor into attributes of the mesh.

t::geometry::TriangleMesh::GetNonManifoldEdges mimics the logic of the
legacy method.

t::geometry::TriangleMesh::RemoveNonManifoldEdges follows the logic of
the legacy method but there are a few differences:
* the main difference is that the outer while-loop is removed. I don't
  see how after the first iteration any edge can have more than 2
  adjacent triangles, which makes the further iterations unnecessary.
* I count triangles with non-negative areas immediately and do not rely
  on the total number of adjacent triangles (which would also include
  triangles marked for removal).
* To choose a triangle with the minimal area out of the existing
  adjacent triangles I use a heap structure.

* Use unordered / sorted comparison for GetNonManifoldEdges() test, return empty areas property if there are no triangles.
