<WM_WINDOWPOSCHANGING>: Let tip frames resize without restriction.
(my_create_tip_window, Fx_show_tip): Adjust size for external border.
(my_create_tip_window): Assign tip_window.
(x_create_tip_frame): Use same defaults as X.
(compute_tip_xy): Remove unused variable. Use full screen width.
(Fx_show_tip): Do not double height. Call ShowWindow directly.
(w32_wnd_proc) <WM_MENUSELECT>: Show help echo directly.
(my_create_tip_window): New function.
(x_create_tip_frame, compute_tip_xy): Adapt for Windows.
(Fx_show_tip, Fx_hide_tip) [TEST_TOOLTIPS]: Adapt for Windows.
(describe_command, describe_translation): Add dummy second param.
(describe_map): Call elt_describer with two arguments.
(describe_vector_princ): Add `fun' parameter.
Call it instead of the hardcoded `princ'.
(describe_vector): Add arg `args'.
Pass it as a new second argument to elt_describer.
(x_draw_bar_cursor): If the background color of the glyph under
the cursor equals the frame's cursor color, use the glyph's
foreground color for drawing the bar cursor.
(x_after_update_window_line): Clear internal border in different
circumstances.
(w32_set_vertical_scroll_bar): Check for width and height > 0.
(w32_draw_relief_rect): Correct relief by 1 pixel.
(x_set_glyph_string_background_width): Set
extends_to_end_of_line_p if the row's fill_line_p is set and
drawing the last glyph with DRAW_IMAGE_{RAISED,SUNKEN}.
(x_display_and_set_cursor): If cursor_in_echo_area, use NO_CURSOR
if cursor_in_non_selected_windows is false.
(show_mouse_face): Clean up. Recognize overwritten cursor
differently.
(x_draw_glyphs): Remove parameters REAL_START and REAL_END.
Notice if cursor gets overwritten.
(notice_overwritten_cursor): Renamed from
note_overwritten_text_cursor. Rewritten to take glyph widths
into account, and to take X positions as parameters.
(x_draw_phys_cursor_glyph): Save state of w->phys_cursor_on_p
around call to x_draw_glyphs.
(x_setup_relief_colors): Use `IMAGE_BACKGROUND' and
`IMAGE_BACKGROUND_TRANSPARENT' to calculate the correct background
color to use for image glyph reliefs.
(x_draw_image_relief): Accept zero tool_bar_button_relief.
(glyph_rect): Remove unused variable `area'.
(message_dolog_marker3): New static variables hold three markers.
(syms_of_xdisp): Initialize and staticpro them.
(message_dolog): Use message_dolog_marker1..3 instead of
allocating markers each time. Unchain them when done.
