Flatpak: drop the WebKit NVIDIA export; the binary owns the workaround

/proc/driver/nvidia/version is readable inside the Flatpak sandbox, so the
binary's NVIDIA branch already sets WEBKIT_DMABUF_RENDERER_FORCE_SHM with
the correct runtime gate and the entrypoint's own export is redundant.

Verified with:
  flatpak run --command=cat com.orcaslicer.OrcaSlicer /proc/driver/nvidia/version
which prints the NVRM version (driver 615.71.09) from inside the sandbox.

 **Pitfall.**
+- **Rule:** On NVIDIA reach for `WEBKIT_DMABUF_RENDERER_FORCE_SHM` before
+  `WEBKIT_DISABLE_COMPOSITING_MODE`. **Why:** the proprietary driver cannot back WebKit's hardware
+  DMABUF renderer, leaving web views blank or slow; FORCE_SHM keeps accelerated compositing and only
+  skips the hardware path, while disabling compositing drops it. Threaded scrolling is a separate,
+  release-dependent default (off in 2.44/2.45, on from 2.46). `WEBKIT_DISABLE_DMABUF_RENDERER` is not a
+  substitute — it is read first, leaves the transport set empty (no compositing from 2.44 on, where the
+  X11/Wayland fallback renderers were removed) and has a reported crash path. On Debian/Ubuntu and
+  openSUSE the `isNVIDIA()` patch returns before the FORCE_SHM check, so `WEBKIT_FORCE_DMABUF_RENDERER=1`
+  must clear it first; that variable exists only in those patches. WebKit reads all of these once per
+  process, before the first WebView.
+  The test is `/proc/driver/nvidia/version`, so a hybrid laptop that renders on its iGPU also takes the
+  shared-memory path, which is a per-frame GPU readback rather than zero-copy; exporting
+  `WEBKIT_DMABUF_RENDERER_FORCE_SHM=0` in the environment restores the hardware path.
+  ```cpp

-# Mesh repair — High Level Design
-
-## Purpose and scope
-
-Mesh repair turns a broken triangle mesh into closed, outward oriented shells that bound a solid, so that the
-mesh slices predictably and the other mesh tools (booleans, cut, painting) get valid input. It runs on demand:
-the *Fix Model* command of the context menu of an object or part and of the warning icon in the object list, *Fix
-All* and *Fix All Plates* in the context menu of a plate, the prompt the Cut tool shows when a cut leaves open edges,
-the *Repair and import* choice of texture import, and the `--repair` option of the command line. It is built on CGAL
-and is the only repair the application has, on every platform.
-
-`repair_mesh()` in `src/libslic3r/MeshRepair.cpp` does the work on one `TriangleMesh`, and `ModelVolume::repair()`
-applies it to a part: it replaces the mesh only when the repair changed it, and remaps or drops the painting of a
-replaced mesh. The GUI side, `fix_model_with_cgal_gui()` in `src/slic3r/Utils/FixModelByCgal.cpp`, runs it on a
-worker thread for each volume of an object, or for one volume, behind a progress dialog. `repair_mesh()` reports its
-progress between stages through a callback, which cancels the repair by throwing.
-
-## What the repaired mesh is
-
-The repair keeps what the slicer would print from the input. The slicer fills a layer where the winding number of
-the input surface is not zero (`MeshSlicingParams::SlicingMode::Regular` uses Clipper's nonzero fill rule), so:
-
-- Shells crossing each other print as their union. The repair keeps them as separate shells, as the parts of an
-  object are kept, and makes each of them an outward oriented solid.
-- A shell inside a solid that is oriented like it adds nothing, and the repair removes it.
-- A shell inside a solid that is oriented inward is a cavity, and stays one.
-- A whole mesh turned inside out prints as a solid, and the repair turns it outward.
-
-On top of that, it closes holes and cracks, gives inconsistently oriented triangles the orientation of their
-neighbours, drops degenerate, duplicate and stray flat geometry, and removes small self-intersections inside a shell,
-such as slivers and folds. Where none of this applies, it reports the mesh as unmodified and the caller keeps the
-original mesh, its painting and its object id.
-
-A volume is repaired in place and is never split into several parts: splitting by connectivity would turn a cavity
-into a separate solid part and fill it. Each solid of the result is a shell of its own, so *Split to parts* still
-separates them. Open pieces of the input whose borders meet exactly, which are pieces of one surface rather than
-solids, come out as the one shell they form.
-
-## Pipeline
-
-The input is treated as a triangle soup. Every stage after the first only runs on what the previous ones could
-not settle, so a valid mesh passes through quickly.
-
-### Valid parts first
-
-Parts of the input that are connected by vertex indices and are already closed, consistently oriented 2-manifolds
-skip the soup stages and go straight to the shell stages. Merging their points with coincident points of other
-parts would only make non-manifold junctions out of solids that touch, for example parts of an assembly exported
-together or voxels written as separate cubes.
-
-### Soup clean-up
-
-The rest of the soup has its coincident points merged. Triangles with repeated corners are dropped. Coincident
-triangles of opposite orientation are a wall between two solids touching face to face, so they cancel in pairs;
-of the remaining copies of a triangle one is kept. A connected region that would vanish entirely through
-cancelling is a two-sided export instead (every face written in both orientations), and keeps one copy of each
-triangle.
-
-Open edges then get their vertices welded within a tolerance of 1e-4 of the bounding box diagonal, which closes the
-cracks some exporters leave between triangles that should share corners. A vertex is never welded further than a
-quarter of its shortest edge, so welding cannot collapse fine detail. A soup that stays mostly open after welding has
-cracks wider than that tolerance, and is welded again with ten and then a hundred times the tolerance.
-
-### Work units
-
-The soup is cut into units repaired independently and in parallel: its connected parts, except that open parts whose
-bounding boxes touch share a unit, so that cracks and T-junctions between separately exported patches still close.
-
-### Building the mesh
-
-A unit whose edges are each shared by at most two triangles, running in opposite directions, and whose vertices each
-have a single fan of triangles, becomes a `Surface_mesh` directly. Any other unit is oriented first. Triangles are
-flipped so that neighbours across an edge shared by two of them agree, each part keeping the orientation the
-majority of its area had, which keeps inward oriented cavities inward. Edges where that is impossible or that more
-than two triangles share are cut, and each fan of triangles around a vertex gets its own copy of the vertex. If that
-still leaves an invalid mesh, CGAL's `orient_polygon_soup()` orients the unit instead, and the parts it flipped
-against their majority are reversed back. The linear pass exists because `orient_polygon_soup()` is several times
-slower on large soups that need only a few fixes.
-
-### Closing
-
-Compatible borders are stitched, parts that can be stitched once reversed are merged, and borders still open are
-snapped onto each other within the weld tolerance, which closes T-junctions. Exactly degenerate faces are removed.
-
-Holes are filled last. Planar border loops that face each other in one plane, one inside the other, bound a single
-region, such as a missing annulus at the end of a tube or a cap with features standing on it. Such a group is
-triangulated at once with a 2D constrained Delaunay triangulation that fills only the faces at odd nesting depth,
-so the openings inside the region stay open. The patch is used only if it closes every loop with the orientation
-of the triangles around it. Every other loop is filled on its own with `triangulate_hole()`, which uses a 2D
-constrained Delaunay triangulation when the loop is planar. Otherwise it searches the best triangulation among all
-triangles over the loop for loops of up to 100 edges, and among the triangles of a 3D Delaunay triangulation for
-longer ones, as the full search is cubic in the length of the loop. Beyond 200 edges the full search is not even
-used as a fallback, and a fan around the loop's centroid closes a loop nothing else could.
-
-The closed unit is split into its shells. The largest stays in place and the others are copied out, as converting
-the whole mesh again costs seconds on large models.
-
-### Shells
-
-The shells of all units, together with the valid parts set aside at the start, are handled independently and in
-parallel. Shells enclosing no volume, which hole filling makes out of stray flat patches, are dropped.
-
-Self-intersections inside a shell are removed locally with `experimental::remove_self_intersections()`, which
-remeshes the region around them. It is used only for local defects: a shell whose intersections involve more than
-5 % of its faces is left as it is, and a result that changes the enclosed volume by more than 0.1 % is undone. On
-heavily overlapping ornamental models the remeshing otherwise cuts parts down to slivers, while on genuine defects
-it changes the volume by thousandths of a percent. Overlaps left in place slice correctly. Remeshing can cut
-small pieces off a shell, so a shell it changed is split again and its pieces enclosing no volume are dropped.
-
-Shells crossing others are found through their bounding boxes and an AABB tree per shell, and are made outward
-oriented solids. For every other shell the winding number just outside it is summed from the orientation of the
-shells containing it, tested from a point on its largest face. The shell bounds the solid only if the winding
-number is zero on exactly one of its sides; it is then oriented so that the solid is inside, or dropped otherwise.
-
-Crossing shells are not united. Slicing unites them anyway, uniting them exactly costs tens of seconds on models
-made of many overlapping pieces, and it would fuse parts that *Split to parts* should keep apart.
-
-## Robustness
-
-The repair avoids `experimental::autorefine_and_remove_self_intersections()` and corefinement, which can crash on
-messy input, and uses only steps whose failures it can detect. A step that fails keeps its input. CGAL precondition
-failures surface as `repair_mesh()` returning false with the message as the error. The output is written in float,
-as every mesh in the application is.
-
-The result does not depend on thread scheduling. `libslic3r_cgal` is built with `CGAL_LINKED_WITH_TBB`. Units and
-shells are processed in parallel, but each on its own data, and their results are gathered in a fixed order;
-sorts compare complete keys, and the detected self-intersections are put in order before they are used. Snapping
-stays sequential, as its parallel version gives different results from run to run. Holes are filled with the full
-search wherever it is affordable, because the search among Delaunay triangles can choose between equally good fills
-differently from run to run, so only non-planar holes of more than 100 edges may still vary. On some inputs
-`experimental::remove_self_intersections()` itself places a few vertices differently from run to run.
-
-## Verification
-
-`tests/libslic3r/test_mesh_repair.cpp` covers each kind of defect above on small meshes with known volumes.
