e6bea0cbc7 Redesign tab-bar event processing (bug#41342, bug#41343)
Instead of emitting menu-item keys like [tab-1],
emit normal mouse events like [mouse-1] and [down-mouse-3]
for all mouse clicks issued on the tab-bar.

* lisp/mouse.el (mouse-posn-property): Handle 'tab-bar' posn-area.

* lisp/tab-bar.el (tab--key-to-number): New internal function.

(tab-bar-mouse-context-menu): New commands.
(tab-bar-map): Bind [down-mouse-1] to tab-bar-mouse-select-tab,
[down-mouse-2] to tab-bar-mouse-close-tab,

8a4081c396 Make adjust_frame_size set up frame's new_width/_height too (Bug#17120)
The purpose of this change is to have implied frame size changes
pick up sizes requested by previous explicit size changes not
only after they have been confirmed by the WM but already when
they are initially passed to adjust_frame_size (Bug#17120).

* src/dispextern.h (delayed_size_change): Remove extern.
* src/dispnew.c (delayed_size_change): Make static again.
(do_pending_window_change): Call change_frame_size only if F's
new_size_p flag is set.
(change_frame_size_1): Set/reset F's new_size_p flag
* src/frame.c (adjust_frame_size): Remove extra
inhibit_horizontal/_vertical checks.  Improve the implied
resizes check with INHIBIT equals 2.  Set F's new_width and
new_height and reset F's new_size_p flag when we run
set_window_size_hook with INHIBIT 0 or 1.
* src/frame.h (struct frame): New bit slot new_size_p.
* src/gtkutil.c (xg_frame_resized): Use F's new_size_p flag
instead of delayed_size_change to decide whether to call
change_frame_size.
(xg_frame_set_char_size): Call frame_size_history_extra before
waiting for the ConfigureNotify event.
* src/xterm.c (handle_one_xevent): Use F's new_size_p flag
instead of delayed_size_change to decide whether to call
change_frame_size.

a190b4cfd8 Major rewrite of adjust_frame_size
Have adjust_frame_size pass native frame sizes to backends
instead of text sizes.  Expand frame size history management.
Drop PIXELWISE argument from change_frame_size and convert
native to text sizes only when calling adjust_frame_size.  Use
convention in arguments that -1 instead of 0 means that no size
change is required.  When adjusting frame sizes pick up delayed
size changes (Bug#46827).

* lisp/frame.el (frame-notice-user-settings, make-frame): Don't
set frame size history.
(frame--size-history): Rewrite doc-string.  Handle new formats
of `frame-size-history' entries.
* src/dispextern.h (delayed_size_change): Extern it.
(change_frame_size): Drop last argument from extern.
* src/dispnew.c (delayed_size_change): Make it global.
(handle_window_change_signal): Reformat.  Drop last argument
from change_frame_size call.
(do_pending_window_change, init_display_interactive): Drop last
argument from change_frame_size call.
(change_frame_size_1): NEW_WIDTH and NEW_HEIGHT now specify
native sizes.  Drop last argument PIXELWISE.  Queue a change
when it either differs from F's current pixel sizes or F's
previously queued sizes.  Inject frame_size_history_extra call
when queuing.  Adopt convention that for queued sizes -1 means
that no size change is required.  Convert from native to text
sizes when calling adjust_frame_size.
(change_frame_size): Drop last argument PIXELWISE and drop it
also in change_frame_size_1 calls.
* src/frame.c (frame_size_history_add): Remove.
(frame_inhibit_resize): Remove call to frame_size_history_add.
(set_menu_bar_lines, set_tab_bar_lines): Simplify.  Drop last
argument from change_frame_size call.
(frame_windows_min_size): No more static.
(keep_ratio): Minor rewrite using macros.
(frame_size_history_adjust, frame_size_history_plain)
(frame_size_history_extra): New functions.
(adjust_frame_size): Major rewrite.  Adopt new convention that
negative values for new sizes mean no change.  Pick up delayed
size changes from F's new_width and new_height slots
(Bug#46827).  Call set_window_size_hook with native instead of
text sizes.  Do not sanitize window sizes any more.  Call
frame_size_history_adjust instead of frame_size_history_add.
Always set F's resized_p slot to true.
(make_frame): Initialize new_width and new_height slots to -1.
Simplify setup of initial sizes and an adjust_frame_size call.
(Fframe_parameters): Drop processing F's new_pixelwise slot.
(check_frame_pixels): Reorder to make declarations appear first.
(Fset_frame_height, Fset_frame_width, Fset_frame_size): Pass
explicit width and height values to adjust_frame_size instead of
-1.
(gui_set_frame_parameters): Minor rewrite making sure that
explicit sizes and the corresponding parameter are passed to
adjust_frame_size.  Remove frame_size_history_add call.
(gui_figure_window_size): Drop last two arguments.  Simplify
assignment of initial size.  Set new_height and new_width slots
to -1.  Use adjust_frame_size to set sizes instead of returning
them to caller.
(syms_of_frame): Drop symbols used by frame size history; these
are now built on-the-fly.  Also drop some menu bar related
symbols in favor of Qmenu_bar_lines.
* src/frame.h (struct frame): Remove new_pixelwise.
(SET_FRAME_COLS, SET_FRAME_LINES, SET_FRAME_WIDTH)
(SET_FRAME_HEIGHT): Remove macros.
(frame_size_history_add): Remove externs.
(frame_windows_min_size, frame_size_history_plain)
(frame_size_history_extra): Add externs.
(FRAME_WINDOWS_WIDTH, FRAME_WINDOWS_HEIGHT): Rename to
FRAME_INNER_WIDTH and FRAME_INNER_HEIGHT.
(gui_figure_window_size): Drop last two arguments from
extern.
* src/gtkutil.c (xg_frame_resized): Rename arguments to WIDTH
and HEIGHT.  Consult delayed_size_change to handle case where
WIDTH and HEIGHT do not match F's new_width and new_height
values.  Call change_frame_size with native sizes and without
PIXELWISE argument.  Instead of frame_size_history_add call
frame_size_history_extra.
(xg_frame_set_char_size): WIDTH and HEIGHT are native sizes now;
fix adjust_frame_size call accordingly.  Instead of
frame_size_history_add call frame_size_history_extra.
(style_changed_cb): Call xg_frame_set_char_size with native
instead of text sizes.
(tb_size_cb): Remove frame_size_history_add call.  Call
adjust_frame_size with INHIBIT 5.
(free_frame_tool_bar, xg_change_toolbar_position): Remove
frame_size_history_add call.
(update_frame_tool_bar): Call adjust_frame_size with INHIBIT 2
and let it handle frame_inhibit_implied_resize and
fullheight/-width.  Remove frame_size_history_add call.
* src/keyboard.c (Fsuspend_emacs): Call change_frame_size with
native sizes.
* src/nsfns.m (ns_set_tool_bar_lines): Call adjust_frame_size
with INHIBIT 2 and let it handle frame_inhibit_implied_resize
and fullheight/-width.  Remove frame_size_history_add call.
(Fx_create_frame): Drop two last arguments in
gui_figure_window_size call.  Do not SET_FRAME_WIDTH and
SET_FRAME_HEIGHT, the adjust_frame_size in
gui_figure_window_size did that already.
* src/nsterm.m (ns_set_window_size): Drop PIXELWISE argument and
its processing; WIDTH and HEIGHT represent native pixel sizes
now.  Call change_frame_size with native sizes.  Remove call to
frame_size_history_add.
([EmacsView viewDidResize:]): Call change_frame_size with native
sizes.
* src/term.c (Fresume_tty): Call change_frame_size with native
sizes.
* src/termhooks.h (*set_window_size_hook): Drop last argument
PIXELWISE.
* src/w32fns.c (w32_change_tab_bar_height)
(w32_change_tool_bar_height): Fix handling of these in the initial
phase before they have been resized at least once.
(Fx_create_frame, w32_create_tip_frame): Drop two last arguments
in gui_figure_window_size call.  Do not SET_FRAME_WIDTH and
SET_FRAME_HEIGHT (or SET_FRAME_COLS and SET_FRAME_LINES), the
adjust_frame_size in gui_figure_window_size did that already.
* src/w32inevt.c (resize_event, maybe_generate_resize_event):
Pass native sizes to change_frame_size.
* src/w32term.c (w32_read_socket): When WM_WINDOWPOSCHANGED pass

(w32_set_window_size): Drop argument PIXELWISE and its
processing; WIDTH and HEIGHT are native sizes now.  Remove
frame_size_history_add calls.  Pass native sizes to
change_frame_size.
* src/widget.c (set_frame_size): Set width and height of widget
directly.  Call frame_size_history_plain instead of
frame_size_history_add.
(update_from_various_frame_slots): Call
frame_size_history_extra.
(EmacsFrameRealize): Call frame_size_history_plain.
(EmacsFrameResize): Call change_frame_size with native sizes.
Call frame_size_history_extra instead of frame_size_history_add.

with FRAME_INNER_HEIGHT.
(redisplay_tab_bar): Don't set tab_bar_redisplayed when we did
not redisplay it.
(redisplay_tool_bar): Don't call it for external tool bar.
Don't set tool_bar_redisplayed when we did not redisplay it.
(redisplay_window): When the tool bar is external call
update_frame_tool_bar directly.
* src/xfns.c (x_set_menu_bar_lines): Call adjust_frame_size only
if number of menu bar lines changed and fix 6th argument.
(x_change_tab_bar_height, x_change_tool_bar_height): Fix
handling of these in the initial phase before they have been
resized at least once.
(Fx_create_frame, x_create_tip_frame): Drop two last arguments
in gui_figure_window_size call.  Do not SET_FRAME_WIDTH and
SET_FRAME_HEIGHT (or SET_FRAME_COLS and SET_FRAME_LINES), the
adjust_frame_size in gui_figure_window_size did that already.
* src/xmenu.c (update_frame_menubar): Fix 6th arg of
adjust_frame_size call.
(free_frame_menubar): For Motif frames fix fullscreen and
`frame-inhibit-implied-resize' handling.  Fix 6th arg of
adjust_frame_size calls.
* src/xterm.c (x_net_wm_state): Remove call to
frame_size_history_add.
(handle_one_xevent): For PropertyNotify and UnmapNotify events

ff7b1a133b Add distinct controls for child frames' borders (Bug#45620)
The background of the 'child-frame-border' face instead of the
'internal-border' face now controls the color of child frames'
borders.

The 'child-frame-border-width' frame parameter is now used for the
width of child frames' borders instead of internal-border-width',

9fe2bdb88a Consolidate #RGB string parsers
Use a single parser of color strings in the #RGB, rgb:R/G/B and

error-checking was spotty, handling of the rgbi: format not always
present, and normalization of the result was sometimes incorrect.

43282a6772 Remove UNSIGNED_CMP
I added this macro in 2011 to fix some signedness comparison bugs.
However, it’s a weird macro and the bugs can be fixed in a
more-straightforward way.  This helps performance slightly (0.5%) on my
platform (Fedora 31 x86-64, GCC 9.3.1 with -O2).
* src/casefiddle.c (do_casify_natnum): Use simple comparison
instead of UNSIGNED_CMP.
* src/character.h (CHAR_VALID_P, SINGLE_BYTE_CHAR_P, CHAR_STRING):
* src/composite.h (COMPOSITION_ENCODE_RULE_VALID):
* src/lisp.h (ASCII_CHAR_P):
Now an inline function, and uses simple comparison instead of
UNSIGNED_CMP.
* src/dispextern.h (FACE_FROM_ID, FACE_FROM_ID_OR_NULL)
(IMAGE_FROM_ID, IMAGE_OPT_FROM_ID): Move these to ...
* src/frame.h (FACE_FROM_ID, FACE_FROM_ID_OR_NULL)
(IMAGE_FROM_ID, IMAGE_OPT_FROM_ID): ... here, and make them
inline functions that no longer use UNSIGNED_CMP.
* src/keyboard.c (read_char): UNSIGNED_CMP is not needed here
since XFIXNAT always returns a nonnegative value.
* src/lisp.h (UNSIGNED_CMP): Remove; no longer used.

c90975f92f Fix initialization of user-defined fringe bitmaps in daemon mode
* src/fringe.c (gui_init_fringe): Rename from w32_init_fringe
or x_cr_init_fringe, and make unconditionally compiled; all

the standard bitmaps.
Suggested by Liam Quinlan <liamkquinlan@gmail.com> in
https://lists.gnu.org/archive/html/emacs-devel/2019-08/msg00259.html.

74a5a332fe Support native image transforms on MS-Windows
This changeset also rearranges native image transform code
for other platforms to make it cleaner, and also removes
the support for native cropping.  For the discussions, see
https://lists.gnu.org/archive/html/emacs-devel/2019-06/msg00242.html

* src/w32term.c (w32_image_rotations_p, transform): New functions.
(w32_draw_image_foreground): If image rotation is requested
and supported, call PlgBlt to transform the image.
(w32_initialize): Populate the PlgBlt function pointer if it
is supported.
* src/w32term.h (w32_image_rotations_p): Add prototype.
* src/dispextern.h (struct image) [HAVE_NTGUI]: New member xform.
* src/image.c (compute_image_rotation): Renamed from
image_set_rotation.  Only compute and returns the rotation
angle; leave the matrix calculation for later.  Log an error
message if the :rotation parameter is not a number.
(image_set_crop): Function deleted.  We no longer support
native cropping, as one can display an image slice instead.
(image_set_transform): Compute the transform matrix in its
entirety here, in two variants: one for XRender and Cairo, the
other for NS and MS-Windows.  call compute_image_size and
compute_image_rotation internally.
(lookup_image) [HAVE_NATIVE_TRANSFORMS]: Call only
image_set_transform.  No need to pass the transform matrix to
image_set_transform.
(Fimage_transforms_p): Return a list of transform capabilities
rather than a simple boolean.  Support TTY frames as well.
* src/nsimage.m (setTransform:): Don't invert the matrix, as
it is already inverted in image.c.

* test/manual/image-transforms-tests.el (test-cropping): State
in the text that only ImageMagick supports cropping.

* doc/lispref/display.texi (Image Descriptors): Update the
documentation of native image transforms.
(ImageMagick Images): Move the description of ':crop' here.

* etc/NEWS: Minor copyedits of the feature announcement.

7c26e0b18d Fix overflow issues in image rotation
Also, do some refactoring to simplify code.
* src/dispextern.h (INIT_MATRIX, COPY_MATRIX, MULT_MATRICES): Remove.
* src/image.c (matrix3x3): New type, replacing all uses of 3x3 double.
(matrix3x3_copy, matrix3x3_mult): New functions, replacing

b2b1ccb86d Introduce Emacs_Pix_Container and Emacs_Pix_Context typedefs
Emacs_Pix_Container is a pointer to a struct representing pixmap data
on the backend.  Emacs_Pix_Context is the context for the
bitmap/pixmap on the backend.  Only w32 currently makes this
distinction; they are otherwise the same type.

* src/dispextern.h: Remove XImagePtr in favor of
using XImage* directly. Rename XImagePtr_or_DC to Emacs_Pix_Context.
[HAVE_X_WINDOWS] Alias Emacs_Pix_Container and
Emacs_Pix_Context to XImage*.
[HAVE_NS] Alias Emacs_Pix_Container and Emacs_Pix_Context to trivial
Emacs_Pixmap definition.
