#ifdef USE_MMX
Most of this patch is based on a patch by Havoc Pennington (hp@redhat.com) 2000-04-11 Federico Mena Quintero <federico@helixcode.com> Most of this patch is based on a patch by Havoc Pennington (hp@redhat.com) to make GdkPixbuf's structures opaque and to remove the libart dependency. * gdk-pixbuf/gdk-pixbuf.h: Removed the public structures. (GdkColorspace): New enum that for now only contains GDK_COLORSPACE_RGB. (GdkPixbufDestroyNotify): New type for the pixbuf's pixels destroy notification function. (GdkInterpType): New num with interpolation types. * *.[ch]: Replace the libart stuff with our own stuff. * pixops/*.[ch]: Likewise. * gdk-pixbuf/gdk-pixbuf-private.h: New file with the private declarations of the GdkPixbuf structures. * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_new_from_art_pixbuf): Removed function. (gdk_pixbuf_get_format): Constify. (gdk_pixbuf_get_n_channels): Constify. (gdk_pixbuf_get_has_alpha): Constify. (gdk_pixbuf_get_bits_per_sample): Constify. (gdk_pixbuf_get_pixels): Constify. (gdk_pixbuf_get_width): Constify. (gdk_pixbuf_get_height): Constify. (gdk_pixbuf_get_rowstride): Constify. * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_copy): New function to copy a pixbuf. * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Added a bits_per_sample argument; currently only 8 bits per sample are supported. * gdk-pixbuf/gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_pixbuf): New accessor. (gdk_pixbuf_frame_get_x_offset): New accessor. (gdk_pixbuf_frame_get_y_offset): New accessor. (gdk_pixbuf_frame_get_delay_time): New accessor. (gdk_pixbuf_frame_get_action): New accessor. * gdk-pixbuf/gdk-pixbuf-render.c (gdk_pixbuf_render_pixmap_and_mask): Instead of returning a solid mask rectangle for pixbufs without an alpha channel, set the *mask_return to NULL. * gdk-pixbuf/gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): Constify. * gdk-pixbuf/gdk-pixbuf-scale.c: Fix includes. * gdk-pixbuf/gdk-pixbuf-scale.c (gdk_pixbuf_scale): Added some preconditions. Maybe we should also check for the colorspace, bits per pixel, and such. (gdk_pixbuf_composite): Likewise. (gdk_pixbuf_composite_color): Likewise. (gdk_pixbuf_scale_simple): Likewise, and fail gracefully if we cannot allocate the new pixbuf. (gdk_pixbuf_composite_color_simple): Likewise. * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): Use art_rgb_rgba_affine() or art_rgb_affine() since we no longer have an ArtPixBuf. * gdk-pixbuf/io-bmp.c: Fix includes. * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Fixed cast in an lvalue. * TODO: Populated. * configure.in: Removed checks for libart. * gdk-pixbuf/Makefile.am: Removed references to libart. (noinst_HEADERS): Added gdk-pixbuf-private.h. * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Incremented the version number of the libtool library to indicate that this definitely is not compatible with the old usage. I know you love me. I know you do. * configure.in: Bumped version number to 0.7.0. * README: Updated. * gdk-pixbuf-config.in (--libs): We no longer require libart. * DEPENDS.libgdk_pixbuf: We no longer depend on libart. * gdk-pixbuf.spec.in: Updated, but I don't guarantee anything.
