Turns every colour of the picture around the colour wheel without changing
how light it is. This matters more here than in a photo editor: the filament
set is fixed and arbitrary, so hue is what lets the picture meet the palette
rather than the other way round. With orange loaded but no red, a small turn
puts the reds onto the orange instead of onto whatever happens to be nearest.
Implemented as Rodrigues' rotation of the colour about the grey axis, then
the Rec. 709 luma is restored exactly: the rotation preserves R+G+B, not the
weighted luma, and without the correction turning the wheel would also change
which areas read as light and dark.

The reddish brick moves onto a different filament in each direction and the
surface does not move.
The first cut was the displacement panel with depth hidden, which left the
brushes, the eight layer slots, the UV editor, seams, tiling and the
mesh-preparation sections in a tool that needs none of them, and offered no
way to correct the picture at all. This replaces that panel and adds the
corrections.
The flow is now: load a picture, click the model to put it there, adjust it,
press Apply.
- The Image tool gets its own window, render_image_input_window(), defined in
GLGizmoImage.cpp. on_render_input_window() dispatches to it on the first
line, so the displacement panel goes back to exactly what it was rather
than being threaded with tests for which tool is drawing.
- A click places the picture: the tool pins SMART_FILL with a pointer cursor,
so one click floods the surface it lands on out to the first fold sharper
than the Spread angle. No brush, no erase toggle.
- Projection keeps Flat, Around, Ball and From view. Unwrap is left out and a
layer arriving on it falls back to Flat: seams, islands and the UV pane are
an editor's worth of interface for a tool that wants a click and a slider.
- The preview is pinned to the fast one. With no relief to build it is both
instant and exactly the final colour, since the shader's colour path does
not depend on depth_mm.
- The window shows only what this case needs: the picture, Spread, the four
projections, Size, Rotation, the corrections, Apply and Close.
Colour correction is new in libslic3r. TextureDisplacementLayer gains
brightness, contrast, saturation, gamma and color_invert, all defaulting to
the identity, and apply_color_adjustments() applies them to an image's RGB
only, never to the height: a brightness slider has no business moving
geometry. It runs at the single point every bake and preview job reads a
layer's colour from, prepare_sampleable_layers(), and at the two caches that
would otherwise miss a change the image_data pointer does not show: the fast
preview's GPU texture and the mix ranking.
Measured with the texture-bake harness, one cube face painted with a colour
image, four filaments:

image, brightness +0.5 8204 1068 0.000004 4:100%
image, contrast +0.8 22688 15552 0.000007 1:75% 2:24% 3:1%

image, negative 8204 1068 0.000004 4:100%
Max offset is the distance from every output vertex to the original surface,
not a vertex-array diff: the bake refines, so a new vertex only counts as
unmoved if it lies in the old surface. Every correction moves which filaments
the picture prints in, and none of them moves the surface.
The green highlight and tint no longer cover a colour preview, and return while a stroke is
painted. The Fast view also keeps the other parts of a multi-part object.
The new Mixed colors setting caps how many mixed filaments a bake adds. They are picked from the
texture's colours, and only the ones the bake paints with are created. Previewing no longer creates
filament slots, both previews show a mix in its slot's colour, and the bake paints each mix with the
slot it actually got.
* Remove Unused Project Includes and Forward-Declare Where a Type Is Only Referenced
Generated with include-what-you-use and applied conservatively. Only OrcaSlicer's own headers, the ones under src/ and tests/, are removed or forward-declared; standard-library and third-party includes are left alone. An include is removed only when both the Release and the Debug configuration leave it unused, never from inside a conditional block, and never from a file with platform-specific blocks, which only gain includes. Files whose only use of a header sits behind a feature or debug macro (libvgcode's OpenGL ES and marker code, the ARACHNE/TESTS_EXPORT_SVGS debug output) keep their includes.
clonable_ptr.hpp gains #pragma once; it had no include guard and was only safe while Config.hpp was its sole includer.
* Remove Unused Project Includes From Files With Platform-Specific Code
A Linux include-what-you-use run cannot see the code inside _WIN32, __APPLE__ or __linux__ blocks, so its verdict is only taken where nothing the removed header declares, directly or through what it includes, is named inside those blocks. Removals also have to hold in both the Release and Debug configuration and never touch a line inside a conditional block.
* Restore the libslic3r Precompiled Header and Direct Includes Lost in the Platform Pass
The platform-file pass treated pchheader.hpp as an ordinary header and
emptied it, and left GUI_Preview.hpp and 14 other files relying on
headers they no longer reached directly.
* Restore MainFrame.hpp in ParamsDialog.cpp for the Windows-Only Reparent Call
* Include Headers That Files Reached Through Ones the Cleanup Removed
* Drop Includes Duplicated by the Cleanup or by Main's Own Additions
* Leave PreciseSeam.cpp as Main Has It After the Precise Seam Rework
* Add Missing Includes Across src/libslic3r
Every libslic3r source and header now directly includes the headers declaring what it uses, rather than relying on the precompiled header or transitive includes. Generated with clang-tidy misc-include-cleaner, with libslic3r headers spelled libslic3r/... so they resolve outside the library's private include paths. MultiMaterialSegmentation.hpp, Support/SupportParameters.hpp and Format/STEP.hpp are made self-contained by hand.
* Make the libslic3r Headers Compile on Their Own
Each now includes, or forward-declares, what it uses instead of relying on what its includers happened to include first. Left out: I18N.hpp, which errors on purpose when included from GUI code, and VoxelizeCSGMesh.hpp and SLA/bicubic.h, which nothing includes and which no longer compile at all.
* Add the Includes Missing From the Hand-Fixed libslic3r Headers
clang-tidy would not edit these headers while they failed to compile on their own, so the first pass skipped them. With the headers now self-contained, a second pass adds the rest.
* Keep Windows Setup Ahead of the Added libslic3r Includes
Print.cpp and Thread.cpp open with a _WIN32 block that has to come first; without the precompiled header, Print.cpp otherwise reaches windows.h through OCCT with NONLS defined and boost/regex fails. OpenVDBUtils.cpp and SLA/SupportTreeBuilder.cpp had includes inside #ifndef NOMINMAX, which libslic3r defines on Windows, so those were skipped there. .clang-tidy also ignores the MSVC STL and UCRT internals, Boost.Multiprecision's fwd.hpp and CPython's Windows include directory.
* Re-Add libslic3r Includes After the Clipper2 2.0.1 Migration
Rebasing onto main took main's version of the files the Clipper2 migration rewrote, so their added includes are restored here, along with includes for main's new code. Clipper2's individual headers are now ignored by clang-tidy: they only build the Z variant through clipper2_z.hpp, which defines USINGZ first, so including clipper.core.h and the like directly broke ClipperZUtils.cpp.
Meeting the triangle budget by merging flat faces alone no longer raises the warning, and the
warning now quotes the budget instead of the triangle count left after the flat faces were merged.
Relief preserved from an earlier bake is counted on top of the budget
instead of eating into it: baking a second area went from ~214 k
triangles to the ~1000 k it was given.
When the resolution needs more triangles than the budget allows, it is
said before the bake under Resolution and again afterwards.
- Bake: each layer is sampled only on its own painted area; analytic
projections used to stack every layer over every painted region, so the
top layer's texture showed on all of them (colour sampler too)
- Auto resolution follows the texture's texel size and sharpness again
- Unwrap: charts cut by each face's own normal (a cube gives 6 islands, not
12 triangles); non-disk charts (tubes, closed shells) are split until they
flatten; connected nets test real triangle overlap, grow from the largest
chart and are packed side by side
- UV edits are stored per unwrapped copy, so dragging a seam vertex no
longer moves its copies in neighbouring islands
- UV pane: tool strip with unwrap settings moved in from the panel, sharp
HiDPI icons, clearer island/edge/selection drawing with hover, texture
picker from the thumbnail, texture no longer lost on reopen (GL state
from the 3D view, background upload retries)
- Panel: whole-model select/erase as icons in the tools row; inactive
layers' paint shown muted; colour textures shown in colour in the picker
- Built-in displacement texture library
- Tests for unwrap segmentation, connected nets, UV edits and per-layer
sampling
