new position.
Sync with xterm.c:
(notice_overwritten_cursor): Renamed from note_overwritten_text_cursor.
Rewritten to take glyph widths into account.
(x_y_to_hpos_vpos): Add parameter BUFFER_ONLY_P.
(fast_find_string_pos): New function.
(fast_find_position): Return the correct vpos. Add parameter STOP.
In the final row, stop before glyphs having STOP as object.
Don't consider glyphs that are not from a buffer.
(fast_find_position) [0]: Add a presumably more correct version for after 21.1.

DRAW is DRAW_IMAGE_RAISED.

actually redrawn. Make the function static. Reset
dpyinfo->mouse_face_overlay otherwise note_mouse_highlight might
optimize away highlighting if we pass over that same overlay again.

to detect a case where we have to highlight a different region
despite not having left the currently highlighted region.
Set mouse_face_overlay in the x_display_info. Avoid changing the
mouse pointer shape when show_mouse_face has already done it, or
there is no need. Handle mouse-face and help-echo in strings.

movement event generation.
(w32_initialize_display_info): Initialize the x_display_info's

fully obscured or not.

only.
(x_insert_glyphs): Call window_box_left to obtain the left
x-coordinate of the area to shift.
characters the same as ASCII and latin-1.

border width is zero.
(x_new_font): Don't change a tooltip's size.

true for images with `:ascent 100'.
(x_set_mouse_face_gc): If the last used mouse face has gone in the
meantime, use face MOUSE_FACE_ID.
If first glyph isn't a character glyph, use the ASCII NUL
character to determine the face.
(expose_area): Do not treat left margin specially.
(note_mode_line_highlight): If no local_map, check global keymap.
(note_mouse_highlight): Initialize overlay.
(clear_mouse_face): Don't return if tip_frame is non-nil.
(show_scroll_bars): Remove unused function.
(w32_read_socket) [WM_KILLFOCUS]: Set help_echo to Qnil.
(x_draw_bar_cursor): Remove extra test for out of bounds cursor.
Clip to row.
(x_erase_phys_cursor): Don't apply XWINDOW to variable that may be nil.
(x_free_frame_resources): Unload relief colors.
a composition is not found, use 1 pixel dot ascent and 0 dot
descent value to avoid displaying terribly tall empty boxes.
(expose_area): Pass x-coordinate relative to the exposed
area to x_draw_glyphs instead of a window-relative coordinate.
(w32_alloc_lighter_color): Use new brightness calculations from
xterm.c. Scale delta to be in the range expected by W32.

(tool_bar_items): Fetch the keymap rather than using keymapp.
(read_key_sequence): Use KEYMAPP.
* intervals.c (get_local_map): Use get_keymap rather than following
function-indirections explicitly.
* doc.c (Fsubstitute_command_keys): get_keymap_1 -> get_keymap.
cached information in emulated XFontStruct to handle common cases
quickly. Do not allocate XCharStruct for return.
(w32_native_per_char_metric): New function.
(w32_bdf_per_char_metric): Fill in supplied XCharStruct instead of
allocating one.
