position. Always get the full ascent / descent of the
corresponding row, to return reliable rtop and rbot values.
(back_to_previous_visible_line_start): Fix 2005-01-18 change.
Must look one character back, as back_to_previous_line_start
returns position after the newline.
(move_it_vertically_backward): Fix heuristic for when to move further
back in case line_height * 2/3 is larger than window height.
(cursor_row_fully_visible_p): Rename make_cursor_line_fully_visible_p
as it does not do anything anymore. Add arg current_matrix_p to
use current matrix rather than desired matrix when set.
(try_cursor_movement): Don't scroll to make cursor row fully
visible if cursor didn't move. This avoids unexpected recentering
in case of blinking cursor or accepting process output.
Use current matrix to check cursor row visibility.
(redisplay_window): Fix whether to recenter or move to top in case
cursor line is taller than window height.
(find_first_unchanged_at_end_row): Stop search if we reach a row
which not enabled (instead of abort).
(setup_for_ellipsis, handle_single_display_spec)
(handle_composition_prop, next_overlay_string)
(get_overlay_strings, reseat_1, reseat_to_string)
(next_element_from_ellipsis, BUFFER_POS_REACHED_P)
(in_display_vector_p, display_line, get_next_display_element):
Change it->method from function pointer to enum.
(get_next_element): New array to map it->method to function.
(get_next_display_element): Use it.
(set_iterator_to_next): Use switch instead of if/else chain.
* w32select.c: Summary: Thorough rework to implement Unicode
clipboard operations and delayed rendering.
Drop last_clipboard_text and related code, keep track of
ownership via clipboard_owner instead. Drop old #if0
sections.
(DEFAULT_LCID, ANSICP, OEMCP, QUNICODE, QANSICP, QOEMCP)
(clipboard_owner, modifying_clipboard, cfg_coding_system)
(cfg_codepage, cfg_lcid, cfg_clipboard_type, current_text)
(current_coding_system, current_requires_encoding)
(current_num_nls, current_clipboard_type, current_lcid): New
static variables.
(convert_to_handle_as_ascii, convert_to_handle_as_coded)
(render, render_all, run_protected, lisp_error_handler)
(owner_callback, create_owner, setup_config)
(enum_locale_callback, cp_from_locale, coding_from_cp): New
local functions.
(term_w32select, globals_of_w32select): New global functions.
(Fw32_set_clipboard_data): Ignore parameter FRAME, use
clipboard_owner instead. Use delayed rendering and provide
all text formats. Provide CF_LOCALE if necessary.
(Fw32_get_clipboard_data): Handle CF_UNICODETEXT and
CF_LOCALE. Fall back to CF_TEXT, if CF_UNICODETEXT is not
available. Force DOS line-ends for decoding.
(Fx_selection_exists_p): Handle CF_UNICODETEXT.
(syms_of_w32select): Init and register new variables.
* w32.h: Add prototypes for globals_of_w32select and
term_w32select. Make the neighboring K&R declarations into
prototypes, too.
* emacs.c: Include w32.h to get function prototypes.
(main): Call globals_of_w32select.
* w32.c (term_ntproc): Call term_w32select.
* mule-cmds.el (set-locale-environment): Remove call to
set-selection-coding-system on Windows.
* s/ms-w32.h: Guard MSC-specific #pragmas with an #ifdef.
type == XA_ATOM, data contains array of int, not array of Atom.
(x_property_data_to_lisp, selection_data_to_lisp_data): Comment
update: data must be array of int for format == 32.
