* src/sfnt.h (SFNT_ROUND_FIXED): New macro.
* src/sfntfont.c (sfntfont_get_glyph_outline): Don't apply
advance width distortion before the glyph is instructed or
decomposed. Round advance width as measured between both
phantom points subsequent to instruction code execution.
(sfntfont_draw): Don't take the advance's ceiling when advancing
origin point.
The var's docstring and etc/NEWS refer to "*Redisplay-trace*",
so better use that (which is also more in line with usual practice
of Emacs buffer names).
The `safe_call/eval` family of functions started its life in `xdisp.c`
for the needs of redisplay but quickly became popular outside of it.
This is not ideal because despite their name, they are somewhat
specific to the needs of redisplay.
So we split them into `safe_call/eval` (in `eval.c`) and `dsafe_call/eval`
(in `xdisp.c`). We took this opportunity to slightly change their
calling convention to be friendly to the CALLN-style macros.
While at it, we introduce a new `calln` macro as well which does
all that `call[1-8]` used to do.
* src/eval.c (safe_eval_handler, safe_funcall, safe_eval): New functions,
Copied from `xdisp.c`. Don't obey `inhibit_eval_during_redisplay` any more.
Adjust error message to not claim it happened during redisplay.
* src/lisp.h (calln): New macro.
(call1, call2, call3, call4, call5, call6, call7, call8): Turn them
into aliases of `calln`.
(safe_funcall): Declare.
(safe_calln): New macro.
(safe_call1, safe_call2): Redefine as compatibility macros.
(safe_call, safe_call1, safe_call2): Delete.
Replace all callers with calls to `safe_calln`.
* src/xdisp.c (dsafe_eval_handler): Rename from `safe_eval_handler`.
Adjust all users.
(dsafe__call): Rename from `safe_call` and change calling convention to
work with something like CALLMANY. Adjust all users.
(safe_call, safe__call1, safe_call2): Delete functions.
(SAFE_CALLMANY, dsafe_calln): New macros.
(dsafe_call1, dsafe_eval): Rename from `safe_call1` and `safe_eval`,
and rewrite using them. Adjust all users.
(clear_message, prepare_menu_bars, redisplay_window): Use `dsafe_calln`.
(run_window_scroll_functions): Don't let-bind `Qinhibit_quit`
since `safe_run_hooks_2` does it for us.
* src/sfnt.c (sfnt_read_glyph): Clear advance and origin
distortion returning an empty glyph.
(sfnt_build_instructed_outline): New parameter *ADVANCE_WIDTH,
in which the glyph's advance width is saved.
(sfnt_interpret_compound_glyph_1): Refine commentary.
(sfnt_verbose, main): Adjust tests.
* src/sfnt.h: Update prototypes correspondingly.
* src/sfntfont.c (sfntfont_get_glyph_outline): If an instructed
outline is available, derive the advance and lbearing from the
measurements within.
(sfntfont_probe_widths): Call sfntfont_measure_pcm to establish
average widths.
(sfntfont_open): Do so after instruction code initialization
completes.
(sfntfont_measure_pcm): Revise commentary.
* src/eval.c (funcall_subr): Help the compiler by reducing aliasing
problems, and compensate for a missed-optimisation bug in LLVM where
switches sometimes forget to use variable range information (reported
in https://github.com/llvm/llvm-project/issues/76085).
* src/sfnt.c (sfnt_interpret_compound_glyph_2): Don't grow the
compound decomposition context for saving compound points into,
since the space for them already exists.
* src/sfnt.c (sfnt_move): Correct commentary.
(sfnt_interpret_control_value_program): Reset dual projection,
freedom and projection vectors, in addition to the reference
points, zone pointers and loop counter.
* src/sfnt.c (sfnt_mul_f26dot6_fixed): Correct rounding
constant.
(sfnt_make_interpreter, SSW, WCVTF, sfnt_compute_phantom_points)
(sfnt_interpret_simple_glyph, sfnt_interpret_compound_glyph_1)
(sfnt_vary_interpreter, sfnt_check_ssw): Account for the
fractional bits in a f26dot6 when computing the interpreter
scale factor.
* src/sfnt.c (sfnt_dot_fix_14): Correct typo in final division.
(sfnt_compute_phantom_points): New parameters S1 and S2, into
which unrounded phantom point coordinates are saved.
(sfnt_interpret_simple_glyph, sfnt_interpret_compound_glyph_2)
(sfnt_interpret_compound_glyph_1): Adjust correspondingly.
* src/sfntfont.c (sfntfont_get_glyph_outline): Delete redundant
branch.
* src/treesit.c (treesit_traverse_child_helper):
Do not call treesit_traverse_sibling_helper when the named node is
required and the last child is the named node.
Otherwise treesit_traverse_sibling_helper will move cursor to the
previous sibling and last node will be skipped.
* test/src/treesit-tests.el (treesit-search-subtree-forward-1):
(treesit-search-subtree-backward-1):
Add tests.
Let the caller tell us clearly where is the base of the backtrace,
if it's not `debug`. This is done by passing a new `:backtrace-base`
keyword argument to `debug`.
Then use this info systematically in all the places where we access
the real C-level backtrace, to try and avoid inconsistencies and brittle
code that tries to enumerate the expected frames we're in.
* src/eval.c (get_backtrace_starting_at): Add support for offsets in the
`base` argument.
(Fbacktrace_debug): Add optional `base` argument.
* lisp/emacs-lisp/debug.el (debug, debugger-frame, debugger-frame-clear):
Use `debugger--backtrace-base` when calling `backtrace-debug`.
(debugger-setup-buffer): Use `debugger--backtrace-base`
when calling `backtrace-get-frames`.
(debugger-frame-number): Drop `skip-base` arg, assume it's never nil.
Add sanity check.
(debugger--backtrace-base): Use the `:backtrace-base` info
in `debugger-args`.
(debugger-eval-expression): Adjust call to `debugger-frame-number`.
(debug--implement-debug-on-entry): Pass appropriate `:backtrace-base`.
* src/sfnt.c (sfnt_deltap): Enable deltap instructions again,
since they now serve a purpose.
(sfnt_compute_phantom_points): Round phantom points to match the
behavior of other TrueType scalers.
* src/sfnt.c (sfnt_curve_is_flat): Tighten threshold for flat
curves.
(sfnt_insert_raster_step): Rewrite loop for clarity.
(sfnt_poly_set_steps): New function; fill small spans with a
plain unexceptional loop rather than memset.
(sfnt_poly_steps): Call that function.
(sfnt_verbose, main): Adjust tests such that the scaler can be
selected at runtime.
* src/sfnt.h: Update prototypes.
* src/sfntfont.c (sfntfont_get_glyph_raster)
(syms_of_sfntfont) <sfnt_raster_glyphs_exactly>: New variable.

* doc/emacs/android.texi (Android Environment):
* doc/emacs/cmdargs.texi (General Variables): Mention the manner
in which the default language environment is selected on
Android.
* lisp/startup.el (normal-top-level): If android and
initial-window-system, call android-locale-for-system-language
for the default locale name.
* lisp/term/android-win.el (android-locale-for-system-language):
New function.
* src/androidfns.c (syms_of_androidfns_for_pdumper): New
function.
(syms_of_androidfns) <Vandroid_os_language>: New variable.
Call syms_of_androidfns_for_pdumper both now and after
loading the dump image.
So turns out ts_node_field_name_for_child takes a named node index,
but we were passing it normal index that counts both named and
anonymous nodes. That's what makes the field name all wrong in
treesit explorer.
* doc/lispref/parsing.texi:
(Accessing Node Information): Update docstring.
* lisp/treesit.el (treesit-node-index): Add some unrelated comment.
(treesit-node-field-name): Get named node index rather than all node
index.
* src/treesit.c (Ftreesit_node_field_name_for_child): Update
docstring, use ts_node_named_child_count.
* src/sfnt.c (sfnt_interpret_mdrp): Cease applying cvt
cut in, as this is contrary to the specification.
(sfnt_interpret_simple_glyph): Correct typo.
(main): Revise tests.
* src/sfnt.c (sfnt_build_append): Don't disregard redundant
motion if outline is empty. Problem encountered in the "M"
glyph within Source Code Pro VF Italic.
* doc/emacs/android.texi (Android Environment): Revise for
change.
* src/android.c (initEmacs): Set LANG to either en_US.utf8 or C,
subject to whether the system is newer than Android
5.0 (inclusive).
