Closes Defects item 26 and Performance item 32.
akgl_actor_render set dest.h from curSprite->width, so every actor was drawn
square and a non-square sprite was stretched or squashed. Invisible in the
fixtures because they are all square, so tests/actor.c gets a 48x24 sprite and
a render backend whose draw_texture records the rectangle it is handed instead
of drawing it. That recording backend is the first coverage akgl_actor_render
has had at all -- every other test in the file stubs renderfunc out.
akgl_game_update looped over AKGL_TILEMAP_MAX_LAYERS with the actor sweep
nested inside it and never compared an actor's layer to the layer it was on, so
every live actor's updatefunc ran sixteen times a frame. The sweep is hoisted
out: updating an actor is not a per-layer operation, and
akgl_render_2d_draw_world already walks the layers for the half that is.
AKGL_ITERATOR_OP_LAYERMASK is honoured rather than ignored now, so a caller who
wants one layer can still ask, and gets each of those actors once.
Counting is the assertion, deliberately. The defect was invisible in the frame
total because the tilemap blits are three orders of magnitude larger, so a
timing test would have measured the rasterizer. tests/game.c counts calls into
a stub updatefunc and reports 16 against the old code.
PERFORMANCE.md records the timing side as what it honestly is: the gap between
the akgl_game_update and draw_world rows of the same run, 92 us before and
noise in both directions after. The absolute table is not re-taken -- a later
run on this machine read every row about 15% high, including rows nothing has
touched.
25/25 pass, reindent --check clean.

Closes internal-consistency items 1 through 6, 12 and 13. Every include guard
is _AKGL_<FILE>_H_, every in-project header include is angled, and every
exported function, type and global carries the akgl_ prefix. This is an ABI
break; the soname goes to libakgl.so.0.5. TODO.md carries the full rename
table.
The renames were driven by renaming each declaration and letting the compiler
find the uses, not by pattern substitution: renderer, physics and camera are
also parameter and struct-member names, and a sed would have rewritten
map->physics and every akgl_RenderBackend *renderer parameter without a word.
Item 4 turned out not to be cosmetic. The library exported a global called
renderer and tests/character.c defined an SDL_Renderer *renderer of its own;
the executable's definition preempted the library's, akgl_sprite_load_json
read a SDL_Renderer * through an akgl_RenderBackend *, and every texture load
in that suite failed. The suite reported success anyway, because libakerror's
unhandled-error handler ends in exit(errctx->status), exit keeps only the low
byte, and AKGL_ERR_SDL is exactly 256. So character had been green while
running one of its four tests, and every suite in the tree was unable to fail
on the most common status in a library built on SDL.
Both are fixed. tests/testutil.h gains TEST_TRAP_UNHANDLED_ERRORS(), which
collapses any status a byte cannot carry onto 1, and every suite installs it.
character binds a real backend with akgl_render_2d_bind. Its fourth test then
runs for the first time and fails on a defect it has asserted all along, so
akgl_heap_release_character now walks state_sprites with
AKGL_ITERATOR_OP_RELEASE and destroys the property set before zeroing the slot
-- TODO.md Defects item 21 and half of Carried over item 1.
AKGL_TIME_ONESEC_MS said "one second in milliseconds" and held 1000000, so
akgl_game_state_lock waited roughly sixteen minutes rather than one second. It
is AKGL_TIME_ONEMS_NS now, the budget is its own named constant, and
tests/game.c holds the mutex from a second thread to assert the wait -- the
contended path had no coverage at all.
Headers are self-contained and it is enforced: AKGL_PUBLIC_HEADERS drives both
install() and a generated translation unit per header, so a header that ships
is a header that is checked. Writing that found registry.h, which used
SDL_PropertiesID in eight declarations and included no SDL header.
23/23 suites pass, memcheck is clean, reindent --check is clean.

libakerror 1.0.0 replaced the consumer-sized status-name array with a
private registry and made status-code ownership explicit and enforced.
AKERR_MAX_ERR_VALUE and __AKERR_ERROR_NAMES are gone, and the registry
entry points raise akerr_ErrorContext * instead of returning int. See
deps/libakerror/UPGRADING.md.
The break was not only source-level. libakgl's codes sat at
AKERR_LAST_ERRNO_VALUE + 18 through + 22, and 1.0.0 claimed exactly
those five offsets for its own AKERR_STATUS_* registry codes, so every
AKGL_ERR_* was aliasing a libakerror status. HANDLE(e,
AKGL_ERR_LOGICINTERRUPT) at physics.c:222 would have swallowed a
foreign-name refusal.
- Move the band to AKERR_FIRST_CONSUMER_STATUS (256) as fixed offsets,
so a libc that grows an errno cannot move the codes, and add
AKGL_ERR_OWNER, AKGL_ERR_LIMIT and AKGL_ERR_COUNT to describe it.
- Reserve the range and register the names through the owned entry
points, PASS-ing each: these are AKERR_NOIGNORE, and the old
akerr_name_for_status calls discarded failure silently.
- Drop the AKERR_MAX_ERR_VALUE=256 compile definition.
- Guard on AKERR_FIRST_CONSUMER_STATUS in include/akgl/error.h, which
now includes <akerror.h> so the guard is reliable. The embedded build
is fine, but the find_package path can pick up a stale installed
header, and 1.0.0 has an soname, so that pairing is an ABI mismatch
rather than a compile problem. Same guard libakstdlib already carries.
Registration also moves out of akgl_heap_init into a new akgl_error_init
in src/error.c. It was in the heap pool's initializer only because that
was the first thing akgl_game_init called, and the upgrade turned five
fire-and-forget name calls into a library-wide ownership claim that can
fail. That placement was hiding a defect: game.c raises AKGL_ERR_SDL
when SDL_CreateMutex fails, five lines before akgl_heap_init ran, so the
earliest error path in the library was guaranteed to print "Unknown
Error". akgl_error_init is now the first statement in akgl_game_init.
Callers that drive subsystems directly must call akgl_error_init first;
it is idempotent, so ordering it precisely is not required. The eleven
test suites that relied on akgl_heap_init to name their statuses now
call it explicitly, or their failure messages would have degraded to
"Unknown Error".
Add tests/error.c: assert every code reads back its registered name,
that the name table and AKGL_ERR_COUNT agree, that a foreign owner is
refused with AKERR_STATUS_NAME_FOREIGN and AKERR_STATUS_RANGE_OVERLAP,
and that repeating the init is a no-op. That last one is a live
constraint, not a triviality -- libakerror treats only an identical
reservation as a repeat, so a subset or superset raises.

Mechanical whitespace-only change across src/, include/, tests/, and
util/, applied with scripts/reindent.sh. No behavioral change.
Most files already conformed. The genuine outliers indented at 2 columns
(json_helpers.c, util.c from akgl_rectangle_points onward, assets.c,
staticstring.c, akgl_actor_add_child, util.h, staticstring.h) or used
spaces where the canonical form is a tab (draw.c). cc-mode also re-aligns
line-continuation backslashes in multi-line macros to its default
c-backslash-column, which is required for the tree to be a fixed point of
the indenter.
Verified whitespace-only: `git diff -w` over this change is empty apart
from three trailing blank lines removed at EOF in src/heap.c,
src/registry.c, and tests/tilemap.c. The build produces no new errors and
ctest is unchanged at 13/14, with `character` still the one intentional
failure.
The tree is now a fixed point of `scripts/reindent.sh --check`.
include/akgl/SDL_GameControllerDB.h is generated and excluded.

Raise line coverage from 39.6 to 61.8 percent with four new suites and an
extension to the actor suite, and register every suite through a single
CMake list so a new test file cannot be left out of the coverage fixture.
Give the test targets a build-tree RPATH and prepend the build tree to
LD_LIBRARY_PATH for CTest, so a developer with a previously installed
libakgl.so exercises the library that was just compiled.
Fix six defects the new tests exposed:
- akgl_physics_simulate read self->gravity_time before its NULL check, so a
NULL backend crashed instead of reporting AKERR_NULLPOINTER.
- akgl_game_save transposed CLEANUP and PROCESS, which placed the fclose
inside the PROCESS switch. An ordinary save never flushed or closed its
stream and produced an empty file.
- akgl_game_save_actors wrote each name table terminator from the address of
a single char, emitting stack contents into the save file and a sentinel
the loader could not recognize.
- akgl_game_load_objectnamemap used CATCH directly inside while(1), where the
break leaves the loop rather than propagating, so a truncated name table
loaded as a successful game.
- akgl_Actor_cmhf_up_on and _down_on dereferenced actor->basechar with no
NULL check, unlike their left and right counterparts.
- akgl_actor_logic_movement checked actor twice instead of checking
actor->basechar before dereferencing it.
