2001-05-04 Havoc Pennington <hp@redhat.com> * configure.in: fix some shell typos * gtk/gtkcolorsel.c (gtk_color_selection_destroy): warning fix * gtk/gtkimage.c: handle animations * gtk/gtkcheckbutton.c (gtk_check_button_size_request): request border_width * 2, not just border_width * gtk/gtkscale.c: add "format_value" signal to allow people to override the way values are drawn. (gtk_scale_get_value_size): fix width/height mistake, and compute size from actual displayed text, not from made-up text. * gtk/gtktexttag.c (gtk_text_tag_class_init): fix return type in signal registration * tests/testtext.c: Add "Remove all tags" menu item for testing * gtk/gtktextbuffer.c (gtk_text_buffer_remove_all_tags): implement * demos/gtk-demo/main.c (main): add hack so we can find modules without installing gtk * demos/gtk-demo/textview.c (insert_text): demo font scaling * gtk/gtkcellrenderertext.c: Add "scale" property (font scaling factor) (gtk_cell_renderer_text_set_property): remove some bogus g_object_notify * gtk/gtktexttag.c: add "scale" property which is a font scaling factor * gtk/gtktextlayout.c (add_text_attrs): add font scale attribute to layout * gtk/gtktextiter.c (gtk_text_iter_is_start): rename from gtk_text_iter_is_first 2001-05-04 Havoc Pennington <hp@redhat.com> * pixops/pixops.c (pixops_process): merge fix from stable: Patch from hoshem@mel.comcen.com.au to fix nonzero X offsets. Fixes bug #50371. * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): merge from stable: Patch from OKADA Mitsuru <m-okada@fjb.co.jp> to fix confusion of using "src" instead of "p". (pixops_composite_color_nearest): Use a more accurate (and correct, to begin with) compositing method. This cures checks showing through on images with no alpha. * gdk-pixbuf.c (gdk_pixbuf_fill): fix bug that left some trailing bytes unfilled. * gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints * gdk-pixbuf-loader.h (struct _GdkPixbufLoaderClass): Change area_updated signal to use signed ints. Removed animation-related signals. * io-gif.c, io-gif-animation.h, io-gif-animation.c: Massive rewrite action * gdk-pixbuf-animation.c: Add GdkPixbufAnimationIter to abstract all the pesky details. Remove old frame-based API. Make GdkPixbufAnimation an abstract base class, derived by the loaders.
