that the weights sum up to the correct total without introducing
negative weights.

any progress, leading to an infinite loop.

my temporary 'gdk-pixbuf-io-include.h' hack

don't have strcasecmp()
* gtk/gtktextview.c : to fix crashing on e.g. TextView::find need
to remove the idle funcs in gtk_text_view_destroy (). To reduce
code duplication wrap it in its own function and use it in
gtk_text_view_unrealize () and gtk_text_view_destroy_layout ()
* gdk/win32/gdkdrawable-win32.c : implement the finalize
method like the X11 version does, allow to set_colormap NULL

set_colormap, also some adaption to X11 version :
(gdk_window_hide) call _gdk_window_clear_update_area
(gdk_window_reparent) call _gdk_window_init_position
* gdk/win32/gdkwindow-win32.c (gdk_window_set_geometry_hints) :
call gdk_window_resize() after all hints are set, because the
window resizing process (WM_GETMINMAXINFO) takes all of them into
account

the actual DLL name of libgdk_pixbuf.
(get_libdir): Use it instead of guessing.
* io-xbm.c (gdk_pixbuf__xbm_image_begin_load): Use
g_file_open_tmp() insread of mkstemp().
2001-10-26 Hans Breuer <hans@breuer.org>
* gdk-pixbuf/gdk_pixbuf.def :
* gdk/gdk.def :
* gtk/gtk.def : updated externals
* gdk/win32/gdkpixmap-win32.c : removed duplicate of
gdk_window_lookup implementation. It already was in
gdk/win32/gdkwindow-win32.c
* gdk/win32/gdkproperty-win32.c : made it compile again
after GdkAtom API change
* gtk/gtk/makefile.msc.in : updated

existing UKNOWN_TYPE error. (#58308)
* gdk-pixbuf.h, gdk-pixdata.c: Rename gdk_pixbuf_new_from_stream()
back to gdk_pixbuf_new_from_inline(). Rework docs to try
and be helpful for the common case. (#58308)

chunks in PNG images.
* demos/testpixbuf-save.c
* demos/testpixbuf-scale.c: simple tests for the new PNG tEXt chunk
feature.
* gdk-pixbuf/tmpl/gdk-pixbuf.sgml: adapt to changes in GDK_PIXBUF_ERROR
