* src/xdisp.c (syms_of_xdisp) <make-window-start-visible>: New
buffer-local variable.
(redisplay_window): If 'make-window-start-visible' is non-nil,
don't accept window-start position that is in invisible text or is
covered by a "replacing" 'display' property. (Bug#14582)
* lisp/menu-bar.el (menu-bar-update-buffers): Detect the initial
frame by its special terminal's name. (Bug#53740)

the initial-terminal's name in menu-bar.el.

* src/eval.c (signal_or_quit): Remove the condition in the batch mode section
of not being in dumping or bootstrap, since it is no longer needed. Test that
'debug-early's symbol-function is bound. Ensure there is enough working space
in specpdl and eval_depth.
(syms_of_eval): New DEFSYM for Qdebug_early. Initialise Vdebugger to
Qdebug_early rather than Qnil.

parameters for controlling the crossing mode. Also improve the
accuracy of generated crossing events when the mouse pointer
moves outside the toplevel from an inferior of it. All callers
changed.

(xw_notify_virtual_downwards_until): New parameters for crossing
mode. All callers changed.
* src/eval.c (funcall_subr): Test most likely cases first (conforming
calls to finite-arity or n-adic SUBRs), and the error cases last,
instead of doing it the other way around. Simplify.

correctly.
* src/haikuterm.h (C_FRAME, C_FONT, C_TERMINAL):
(struct haiku_display_info):

* doc/lispref/display.texi (Attribute Functions)
(Face Attributes): Clarify that the :font attribute of a face and
the font returned by 'face-font' are by default for ASCII
characters. (Bug#53664)
* src/eval.c (signal_or_quit): Bind the correct variable, Qdebugger (not
Vdebugger) to Qdebug in the section for errors in batch jobs.
(syms_of_eval): New DEFSYM for Qdebugger.
Rework the code we have in Fdefalias that tries to keep track
of definitions so as to be able to undo them later.
We used to store in `load-history` when an autoload is redefined as
a non-autoload and in the `autoload` symbol property we used to store
the autoload data that used to be used before it got overriden.
Instead, store the history of the function definition of
a symbol in its `function-history` symbol property.
To make this list cheap in the default case, the latest value is not stored
in the list (since it's in the `symbol-function`) and neither is the first
file. So if there's only been a single definition (the most common case),
the list is empty and the property is just not present at all.
The patch also gets rid of the `autoload` vs `defun` distinction in
`load-history` which seems unnecessary (a significant part of the
motivation for this patch was to get rid of the special handling of
autoloads in this part of the code).
* src/data.c (add_to_function_history): New function.
(defalias): Use it. Don't add the `t` entries for autoloads and always
use `defun` regardless of the kind of definition.
Change `Vautoload_queue` to only hold the function
symbols since the rest is now available from `function-history`.
* src/eval.c (un_autoload): Adjust accordingly.

(help-fns--autoloaded-p): Rewrite.
(help-fns-function-description-header): Adjust call accordingly.
* doc/lispref/loading.texi (Where Defined): Remove `autoload` and `t`
entries from `load-history` since we don't generate them any more.
Document the `function-history` which replaces the `autoload` property.
(Unloading): Adjust symbol property name accordingly.
* test/lisp/loadhist-resources/loadhist--bar.el:
* test/lisp/loadhist-resources/loadhist--foo.el: New files.
* test/lisp/loadhist-tests.el (loadhist-tests-unload-feature-nested)

tooltip frames.

hard-coded alpha mask.
(x_term_init): Calculate alpha bits and offset and populate
field appropriately.
* src/xterm.h (struct x_display_info): New fields `alpha_bits'
and `alpha_offset'.
(x_make_truecolor_pixel): Stop hardcoding the value of the alpha
mask.

so xft face ext info gets reset.

(x_xrender_color_from_gc_background): Premultiply alpha with
components if asked for.
* src/xterm.h (struct x_display_info): New atom
`Xatom_net_wm_opaque_region'.
(clone-frame): Use frame-internal-parameters.
(undelete-frame--handle-delete-frame): Instead of using frameset-save,
save frame-parameters except frame-internal-parameters and 'display'
on non-graphic display. Also save window-state from window-state-get.
(undelete-frame): Instead of using frameset-restore,
set default-frame-alist for make-frame (like in clone-frame),
and restore window-state with window-state-put.
* lisp/frameset.el (frameset-session-filter-alist): Append
parameters from frame-internal-parameters with the filter :never.
Remove :name that is now in frame-internal-parameters.
(frameset-persistent-filter-alist): Remove outer-window-id,
parent-id, window-id that are now in frame-internal-parameters,
included here via frameset-session-filter-alist.

future.
