Bind inhibit-modification-hooks to t.
Don't bind (after|before)-change-functions to nil while they run.

Check for fg and bg colors.
(lookup_image): Use search_image_cache. Cache fg and bg colors.
(pbm_load): Another check for invalid image data.

* image.c: Sync to trunk version.
(search_image_cache, uncache_image, image-refresh): New functions.

New functions.
(window_min_size_1, size_window, Fdisplay_buffer)
(Fsplit_window, adjust_window_trailing_edge): Use it to avoid
windows without mode- or header-lines when window-min-height is
too small.
(size_window): Reset nodelete_p after testing it, following an
earlier note by Kim F. Storm.
(display_buffer): Do not set split_height_threshold to twice the
value of window_min_height to avoid changing the value of a
customizable variable. Rather explicitly check whether the
height of the window that shall be splitted is at least as large
as split_height_threshold.
(Fwindow_full_width_p): New defun.
(syms_of_window): Defsubr it.
(Fdisplay_buffer): Use NILP.
