- sleepers3d / sleepers3dplain / sleepers3dbed in eu07.ini: timbers put together from the begin, main and end parts of a model
and stretched to their length, plain sleepers of their own model; tracks whose plain sleepers would touch are laid as one
cluster, lines of timbers led by priority and turned to the bisectors of frogs and crossings at a limited rate, whole timbers
under crossings, split ones between tracks with room to part them, gaps filled per rail and overlaps shortened or dropped;
clusters worked out in a background thread while driving, on demand in the editor
- the ballast can be left out under the beams (sleepers3dbed no)
- blades get their heel and throw from the switch template or blades <heel> <throw> in the scenery; blades of double switches
run on into the track linking them to the next switch
- rail cutting at frogs, wing rails, movable noses and switch crossings done by one carving pass (RailCarve)
- tint of the rail treads applied to the colour only, without the matte band at the frog
- a switch trailed through with a movable nose set the other way derails the vehicle
- self-tests: sleepercheck, sharedzones, beamsnear, throw, sleepersbg

Unused names are commented out; parameters used only on some platforms
are marked [[maybe_unused]].
* refactor(sonar): declare non-mutating member functions const (cpp:S5817)
Virtual functions are left untouched so overrides keep matching.
* refactor(sonar): merge collapsible nested if statements (cpp:S1066)
Comments that preceded the inner if are kept above the merged statement.

* fix(sonar): give polymorphic base classes virtual destructors (cpp:S1235)

* refactor(sonar): add default cases to switch statements (cpp:S3562)
* refactor(sonar): use std::size for array lengths (cpp:S7127)
* refactor(sonar): use std::ranges algorithms and std::erase(_if) (cpp:S6197)

* refactor(sonar): avoid side effects inside typeid operands (cpp:S5279)
* refactor(sonar): drop top-level const from by-value return types (cpp:S5951)
* refactor(sonar): declare variables separately from their type definitions (cpp:S3646)
* refactor(sonar): declare loop counters in the for statement (cpp:S5955)
* refactor(sonar): rely on class template argument deduction (cpp:S6012)
* refactor(sonar): inherit base constructors instead of forwarding them (cpp:S5952)
* refactor(sonar): rename locals that shadow outer declarations (cpp:S1117)
Only local variables and definition parameters are renamed; shadowing
struct fields and enumerators in headers are left for a separate change.
* refactor(sonar): reduce enum qualification with using enum (cpp:S6177)
Applied only where no unqualified name in the block could be captured by
the introduced enumerators.
* refactor(sonar): mark converting constructors explicit (cpp:S1709)
sound_source and the gl::object conversion operators stay implicit; they
are relied upon by copy-list-initialisation and GL calls.
* refactor(sonar): initialise members in initialiser lists or declarations (cpp:S3230)
* refactor(sonar): make read-only local references and pointers const (cpp:S5350)
* refactor(sonar): take read-only pointer and reference parameters as const (cpp:S995)
TTrain command handlers keep their signature, it is fixed by the handler table.
* refactor(sonar): pass expensive-to-copy parameters by const reference (cpp:S1238)
Signatures declared in files touched by PR 206 (Driver.h, EU07.cpp) and
virtual overrides are left unchanged.
* refactor(sonar): use transparent comparators for string-keyed maps (cpp:S6045)
std::unordered_map instances and map types exposed in headers used by
other modules are left as they are.
* fix(sonar): do not use UI text as a printf format string (cpp:S5281)
Text lines containing '%' would otherwise be interpreted as format
specifiers by ImGui::TextColored.
* refactor(sonar): use std::bind_front for callbacks (cpp:S5995)
* refactor(sonar): drop const_cast on string literals passed to the Python C API (cpp:S859)
* refactor(sonar): take read-only string parameters as std::string_view (cpp:S6009)
The Windows messaging helpers keep std::string, they need c_str().
* refactor(sonar): make read-only global tables const (cpp:S5421)
Mutable global state (flags, timers, singletons) is left as is.
* refactor(sonar): replace single-case switch statements with if (cpp:S1301)
* refactor(sonar): format UUIDs and log timestamps with std::format (cpp:S6494, cpp:S5945)
* refactor(sonar): use std::array for local fixed-size arrays (cpp:S5945)
Arrays that are class members or part of headers are left unchanged.
* fix(sonar): test the bearing damage bit, not bit 0 (cpp:S872)
'DamageFlag & dtrain_bearing > 0' parsed as 'DamageFlag & (dtrain_bearing > 0)',
i.e. DamageFlag & 1, so bearing friction reacted to the wrong damage flag.
* refactor(sonar): assorted small fixes
- empty() instead of size() comparisons (cpp:S1155)
- member initialisers in declaration order (cpp:S3229)
- no redundant c_str() when a std::string is accepted (cpp:S7121)
- contains() on associative containers (cpp:S6171)
- const reference instead of a copying range-for (cpp:S6032)
- starts_with() for prefix checks (cpp:S6178)
- no std::move on temporaries (cpp:S5274)
- has_value() on std::optional (cpp:S7172)
- bool literals for bool members (cpp:S5820)
- inline only on the definition (cpp:S3548)
- explicit base access specifier (cpp:S5965)
- explicit element access instead of dereferencing an array (cpp:S7116)
- rely on the C++20 rewritten operator!= (cpp:S6186)
* refactor(sonar): more small fixes
- std::format instead of iostream manipulators in to_string/to_hex_str (cpp:S6495);
output verified identical, negative hex values keep the unsigned form
- remove an empty compound statement (cpp:S108)
- drop an always-false unsigned < 0 branch (cpp:S1768)
- explicit lambda capture (cpp:S3608)
- std::make_unique (cpp:S5950)
* chore: strip stray carriage returns left in TTrain constructor comments
* fix: keep quantize() in its own value type
The S5276 change cast the result of the generic quantize<Type_>() to
unsigned int, which truncated float/double callers (shadow angle slider,
editor rotation snapping, AI speed control steps) and broke negative values.
* fix(sonar): use integer loop counters in segment sampling (cpp:S2193)
* refactor(sonar): clean up issues reported on PR 209
- remove locals left unused after the dead-store cleanup (cpp:S1481, cpp:S1854)
- unnamed unused parameter (cpp:S1172)
- single-use declarations moved into if init-statements (cpp:S6004)
- auto for casted initialisers (cpp:S5827)
- const references and pointers where nothing is modified (cpp:S5350)
- rename structured bindings shadowed by inner declarations (cpp:S1117)
