* src/xfns.c (setup_xi_event_mask): Select for raw keypress
events on GTK 2.
* src/xterm.c (handle_one_xevent): Set pending keystroke time
when a raw event is received.
* src/xterm.h (struct x_display_info): New flag
`pending_keystroke_time_special_p'.
* src/xterm.c (x_dnd_cleanup_drag_and_drop): Always free DND
targets even if waiting for finish.
(x_dnd_begin_drag_and_drop): Free targets correctly when
signalling error and prevent activating drag-and-drop inside a
menu or popup. (It doesn't work.)
* src/image.c (gif_load): Invert the way animated pixmaps are
created: Work on the cached computed-so-far pixmap, and then copy
the entire thing to the ximg with PUT_PIXEL at the end. This
should work across platforms, which the previous version didn't.
* src/image.c (anim_prune_animation_cache): Tweak the destructor
API.
(gif_destroy): New function.
(gif_load): Use a cache to avoid quadratic CPU usage for animated
images (bug#45224).
(webp_destroy): New function.
(webp_load): Use it.
* src/image.c (struct anim_cache, anim_create_cache)
(anim_prune_animation_cache, anim_get_animation_cache): Rename
from webp_cache (etc) to prepare for usage in the gif animation
implementation, too.
(webp_load): Adjust cache usage.
* src/haikufns.c (haiku_create_frame): Cascade from toplevel
frames, since otherwise the positions are wrong anyway, and it
doesn't make sense to cascade from a frame that disappears when
it becomes deactivated.
* src/xterm.c (handle_one_xevent): Set pending times on GTK as
well.
* src/gtkutil.c (xg_widget_key_press_event_cb): Respect pending
keystroke time on XI2.
* src/image.c (init_webp_functions) [WINDOWSNT]: Load Demux
functions from the WebPDemux DLL. Load internal functions where
the public APIs are inline functions defined in the WebP headers.
(WebPAnimDecoderOptionsInit) [WINDOWSNT]: Define to call
'WebPAnimDecoderOptionsInitInternal'.
(WebPDemux): Define to call 'WebPDemuxInternal'.
(WebPAnimDecoderNew): Define to call
'WebPAnimDecoderNewInternal'.
(syms_of_image) <webpdemux>: New symbol.
* lisp/term/w32-win.el (dynamic-library-alist): Add a member for
'webpdemux'.
* src/xterm.c (handle_one_xevent): Attribute core events sent by
input methods like I-Bus to the extension device that caused
them to be sent.
* src/xterm.h (struct x_display_info): New fields
`pending_keystroke_time' and `pending_keystroke_source'.
* configure.ac (HAVE_RSVG): Also include the webpdemux library.
It was new in version 0.4.4, and we require 0.6.0, so it should be
safe.
* src/image.c: Include demux.h.
(enum webp_keyword_index, webp_format): Include :index for
animations.
(init_webp_functions): Add Windows LOAD_DLLs.
(struct webp_cache, webp_create_cache)
(webp_prune_animation_cache, webp_get_animation_cache): New
functions.
(webp_load): Support animated webp images (bug#54242).
* src/xterm.c (x_dnd_do_unsupported_drop): Fix computation of
local value.
(x_dnd_begin_drag_and_drop): Try to own the selection if we do
have a local value.
* src/keyboard.c (gen_help_event, kbd_buffer_store_help_event):
Make sure to initialize the event buffer correctly.
* src/xterm.c (xi_populate_device_from_info): New function.
(x_init_master_valuators): Factor out most of the valuator
tracking code to that function.
(handle_one_xevent): Handle device enable and disable events in
a more detailed fashion.
* src/keyboard.c (kbd_buffer_get_event): Don't dereference f if
nil when generating mouse motion event.
* src/xterm.c (x_dnd_send_enter, x_dnd_send_position)
(x_dnd_send_leave, x_dnd_send_drop, x_send_scroll_bar_event):
Use NoEventMask instead of 0.
* src/xterm.c (x_get_scroll_valuator_delta): Accept a pointer to
a device instead of the device id.
(handle_one_xevent): Pass the previously found device.
* xterm.c (x_set_cr_source_with_gc_foreground)
(x_set_cr_source_with_gc_background): Set operator back to OVER
if alpha-background isn't to be respected.
Make any build on macOS 10.13 and below follow the same drawing path
as the GNUstep port. macOS 10.14 and above will use EmacsLayer.
* src/nsterm.h (EmacsLayer):
* src/nsterm.m ([EmacsView makeBackingLayer]):
([EmacsView unlockFocus]):
([EmacsView windowDidChangeBackingProperties:]):
([EmacsView copyRect:to:]): Remove any code required for macOS 10.13
and below, and fix the #if's to enforce strict separation of the
drawing paths.
(ns_update_end):
(ns_unfocus): Fix #ifs so that flushWindow is called on old macOS
versions as well as GNUstep.
This is the function that marks the C stack. Avoid confusion with the
new mark stack, a stack used in the GC mark phase.
* src/alloc.c (SETJMP_WILL_LIKELY_WORK, SETJMP_WILL_NOT_WORK)
(mark_stack, mark_c_stack):
* src/lisp.h:
* src/thread.c (mark_one_thread): Rename mark_stack to mark_c_stack.
