clip_tail.
* xdisp.c (get_glyph_string_clip_rect): Restrict horizontal clip
region to the area between clip_head and clip_tail.
(draw_glyphs): Record the area that need to be actually redrawn to
the new variables clip_head and clip_tail when there are
overhangs. Set values of these variables to the corresponding
members in struct glyph_string. Refine x coordinates for
notice_overwritten_cursor using clip_head and clip_tail.
* macgui.h (STORE_XCHARSETSTRUCT): New macro.
* macterm.c (mac_compute_glyph_string_overhangs): Implement with
QDTextBounds.
(x_draw_glyph_string): Don't fill the background of the successor
of a glyph with a right overhang if the successor will draw a
cursor.
(XLoadQueryFont): Obtain font metrics using QDTextBounds.
(x_redisplay_interface): Add entry for
compute_glyph_string_overhangs.
(DARWIN): Defined.
* process.c (init_process): Default process-connection-type to
nil on darwin 6 or less, t if it is 7 or higher. This way the
broken pty behavior is still allowed on darwin 6 for interactive
processes for people that know what they are doing.
(init_editfns): Assign new variable operating-system-release
based on call to uname if available.
(get_operating_system_release): Added function to
allow c-level access to operating system release.
* config.h: Regenerated.
* s/darwin.h (PTY_ITERATION): Don't allow PTYs on darwin 6 or
less.
(MIN_PTY_KERNEL_VERSION): Defined minimum kernel version for
using ptys as '7'.
* term/mac-win.el (process-connection-type): Removed.
Controlled now by s/darwin.h:PTY_ITERATION.
(READABLE_EVENTS_FILTER_EVENTS)
(READABLE_EVENTS_IGNORE_SQUEEZABLES): New flags for readable_events.
get_filtered_input_pending, readable_filtered_events): Removed.
(tracking_off): Call readable_events and get_input_pending with
flag READABLE_EVENTS_DO_TIMERS_NOW.
(readable_events): Move code from old readable_filtered_events here,
but check new READABLE_EVENTS_* in argument flags instead of previous
two boolean arguments do_timers_now and filter_events.
If we are doing mouse tracking and the mouse moved, return only if
READABLE_EVENTS_IGNORE_SQUEEZABLES is not set in flags.
(swallow_events): Call get_input_pending with flag
READABLE_EVENTS_DO_TIMERS_NOW.
(get_input_pending): Move code from old get_filtered_input_pending
here. Replace boolean arguments do_timers_now, filter_events with
flags, and pass flags to readable_events. Document new
READABLE_EVENTS_* flags.
(detect_input_pending_ignore_squeezables): New function.
(detect_input_pending_run_timers): Call get_input_pending with flag
READABLE_EVENTS_DO_TIMERS_NOW.
(Finput_pending_p): Call get_input_pending with flags
READABLE_EVENTS_DO_TIMERS_NOW and READABLE_EVENTS_FILTER_EVENTS.
* dispnew.c (update_window, update_frame_1): Replace calls to
detect_input_pending with detect_input_pending_ignore_squeezables
so that redisplay is not paused if the event queue contains only
mouse movements.
* lisp.h: Declare detect_input_pending_ignore_squeezables.
* gtkutil.c (xg_create_frame_widgets): Set initial tool bar height to
38.
(xg_tool_bar_detach_callback): Set toolbar_detached to 1.
(xg_tool_bar_attach_callback): Set toolbar_detached to 0.
(xg_create_tool_bar): Initialize toolbar_detached.
(update_frame_tool_bar): Only set FRAME_TOOLBAR_HEIGHT (f) if
toolbar_detached is zero.
(xg_tool_bar_callback, xg_tool_bar_help_callback)
(update_frame_tool_bar): Cast to EMACS_INT to avoid compiler
warning.
* xselect.c (x_get_foreign_selection, x_fill_property_data)
(Fx_get_atom_name, Fx_send_client_event): Replace XFLOAT with
XFLOAT_DATA to get extract number from Lisp object.
