Project the texture in the model's own orientation, and stop the preview tiling

The bake frame took its orientation from the world, so turning a part on the
plate slid the decoration across its surface. Turning a part is a print-time
decision - clearance, supports, warping - and it should not be a design one.
The frame now takes its orientation from the model and keeps world scale, so a
tile is still tiling_scale printed millimetres whatever the instance's scale.

The rotation is separated out by polar decomposition rather than by assuming
the linear part is a rotation times a scale, since a sheared or mirrored
placement is legal here. A reflection is deliberately left with the scale, so a
mirrored instance still makes the frame's determinant negative and the bake
still flips the normals it derives.

The preview shaders rebuild that frame themselves from a world position, so
they take the same rotation through a uniform; without it the fast preview and
the bake would disagree, which is the class of bug this is fixing. The gizmo's
own way back out to world carries the rotation too, which it did not need to
when the frame was world-aligned.

Tiling in the fast preview:

- the sampler wrap mode was set on the height texture but not on the colour
  texture, which sits on its own unit and is sampled at the same uv. So with
  Tile off the relief stopped at one placement while the colour carried on
  repeating around it.
- outside a single placement the colour then came out black, because a zero
  texture border cannot say "no colour here", only "the colour is black here".
  The shader now tests the uv the way sample_layer_color() does and leaves the
  surface its own colour.

The placement gizmo is a tile of a planar projection, so it is offered only for
the mappings that have one. An unwrap cuts the surface into islands and packs
them, and a model's own UV channel is whatever its author drew: one tile lands
there as an arbitrary curved patch with no rectangle to take hold of. Those two
say so and point at the UV editor instead.

 **Mechanism.** `CLI::run` (`src/OrcaSlicer.cpp`, under `#ifdef __WXGTK__`, before GTK initialises)
-sets the DMABUF workarounds and then branches on `GDK_BACKEND`:
-- **Both paths**, before the split: when `/proc/driver/nvidia/version` exists and the linked WebKitGTK
-  honours the switch (>= 2.44, `WebView::SupportsForceSharedMemory()`), it sets
-  `WEBKIT_DMABUF_RENDERER_FORCE_SHM=1` and `WEBKIT_FORCE_DMABUF_RENDERER=1` non-replacing. The
-  proprietary driver cannot back WebKit's hardware DMABUF renderer, so the shared-memory transport keeps
-  accelerated compositing instead of dropping it; `WEBKIT_FORCE_DMABUF_RENDERER` clears the
-  Debian/Ubuntu/openSUSE `isNVIDIA()` early return, which otherwise returns before the FORCE_SHM check.
-- **Hypervisor guests**, same position: when `is_hypervisor_guest()` (the `hypervisor` flag in
-  `/proc/cpuinfo`) and WebKitGTK >= 2.44, it sets `WEBKIT_DMABUF_RENDERER_FORCE_SHM=1` non-replacing.
-  Virtual GPUs (VirtualBox VMSVGA, VMware, QEMU) cannot back the hardware DMABUF path either, and
-  FORCE_SHM alone was confirmed to fix web views in VirtualBox; the `WEBKIT_FORCE_DMABUF_RENDERER` pair
-  is not needed without the Debian `isNVIDIA()` patch. The flag is x86-only, so ARM guests are not covered.
+branches on `GDK_BACKEND`:
 - **Default path** (`GDK_BACKEND` unset or not starting with `x11`): if wx lacks EGL (`!wxHAS_EGL`) and
-  `WAYLAND_DISPLAY` is set, it forces `GDK_BACKEND=x11`, and in that same branch it sets
-  `WEBKIT_DISABLE_COMPOSITING_MODE=1` non-replacing when the linked WebKitGTK predates 2.42
-  (`WebView::NeedsCompositingWorkaround()`). That forced X11 backend in a Wayland session is the only
-  default-path case that really runs through XWayland; `DISPLAY` and `WAYLAND_DISPLAY` alone do not
-  identify it, because a native Wayland app inherits both. `XInitThreads()` runs only when `DISPLAY` is
-  set.
+  `WAYLAND_DISPLAY` is set, it forces `GDK_BACKEND=x11`; it sets `WEBKIT_DISABLE_COMPOSITING_MODE=1`
+  non-replacing **only** when both `DISPLAY` and `WAYLAND_DISPLAY` are non-empty (a Wayland session with
+  XWayland available — the session, not the backend GTK will pick); `XInitThreads()` runs only when
+  `DISPLAY` is set.
 - **`GDK_BACKEND=x11…` opt-in path**: sets `DRI_PRIME=1` (and the NVIDIA PRIME variables when
   `/proc/driver/nvidia/version` exists), calls `XInitThreads()`, and deliberately does **not** disable
-  compositing, which keeps hardware acceleration for Device / Setup Wizard / login pages.
+  compositing (the comment: the WebKit2GTK XWayland bug appears fixed in WebKit2GTK ≥ 2.42, and leaving
+  compositing on keeps hardware acceleration for Device / Setup Wizard / login pages).
 
 Runtime backend detection elsewhere uses Orca's `is_running_on_wayland()` / `is_running_on_x11()`
 (see `references/platforms.md`), not these environment variables.
 
 **Pitfall.**
-- **Rule:** On NVIDIA and hypervisor guests reach for `WEBKIT_DMABUF_RENDERER_FORCE_SHM` before
-  `WEBKIT_DISABLE_COMPOSITING_MODE`. **Why:** the proprietary driver and virtual GPUs 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
-  // Wrong: kills compositing and threaded scrolling (and can crash on modern WebKit)
-  ::setenv("WEBKIT_DISABLE_DMABUF_RENDERER", "1", false);
-  // Right: keep compositing, skip only the hardware DMABUF path

 `MainFrame` leaves it to a focused control that uses Space itself (text fields, buttons,
 combo boxes), so it opens the dial from the canvases and the tab strip only.
 
-`MainFrame::handle_global_shortcut` skips a chord that `KeyChord::edits_text()` reports
-while a text field has the focus (a wx text entry, spin control, web view or ImGui
-InputText), and skips every chord while an ImGui modal is open, as a wx modal dialog
-would. `ImGuiWrapper::owns_key()` reads the active InputText and the popup stack
-directly, since `WantCaptureKeyboard` lags a frame, and is called only when the focus is on
-a visible canvas from `OpenGLManager::create_wxglcanvas()`.
-
 ## Which event a chord matches
 
 Letters, digits and special keys match on `wxEVT_KEY_DOWN`. Its key codes do not depend
