#include "config.h"
This might seem like a large patch, but it isn't that bad, and nothing should break on Unix/X11. Win32 merge and general portability stuff: * acconfig.h,configure.in: Check for <sys/time.h>. * gdk/win32: New directory (actually, been there for a while). * gtk/fnmatch.c: Include <glib.h> for G_DIR_SEPARATOR, WIN32 and NATIVE_WIN32, and use these. Always case fold on Win32. No backslashed escapes on native Win32. * gtk/{gtk.def,makefile.msc}: New files. * gtk/Makefile.am: Add above new files. * gtk/{gtkaccelgroup,gtkbindings}.c: Include <string.h> instead of <strings.h>. * gtk/{gtkcalendar,gtkitemfactory,gtkpreview,gtkrc}.c: Include config.h. Protect inclusion of <sys/param.h>, <sys/time.h>, and <unistd.h> appropriately. * gtk/gtkdnd.c: Merge in Win32 version (which doesn't do much). Use ABS() (from <glib.h>) instead of abs(). * gtk/gtkfilesel.c: Moved Win32-specific includes after inclusion of gtk (and thus glib) headers, so that WIN32 will be defined. With MS C, include <direct.h> for mkdir prototype. * gtk/gtkitemfactory.c (gtk_item_factory_callback_marshal): Add some casts, needed by MS C. * gtk/{gtklayout,gtkplug}.c: Merge in Win32 version (which isn't implemented). * gtk/gtkmain.c: Include gdk/gdkx.h for GDK_WINDOWING. Include <X11/Xlocale.h> only on X11 platform, otherwise <locale.h>. Use G_SEARCHPATH_SEPARATOR_S and g_module_build_path. * gtk/gtkmain.h: Mark variables for export/import on Win32. * gtk/gtkrange.c (gtk_range_motion_notify): Set mods also in case the event is not a hint, or its window is not the slider. Needed on Win32, at least. * gtk/gtkrc.c: Include config.h and gdk/gdkx.h. Use <locale.h> unless on X11. Skip \r chars, too. Use G_DIR_SEPARATOR and G_SEARCHPATH_SEPARATOR(_S). Use g_path_is_absolute. On Win32, use a subdirectory of the Windows directory as gtk system configuration directory. * gtk/gtkselection.c: No chunks on Win32. * gtk/gtksocket.c: Not implemented on Win32. * gtk/gtkthemes.c (gtk_theme_engine_get): Use g_module_build_path. * gtk/makeenums.h: Include gdkprivate.h after gdk.h. * gtk/testrgb.c: Use dynamically allocated buffer.

This might seem like a large patch, but it isn't that bad, and nothing should break on Unix/X11. Win32 merge and general portability stuff: * acconfig.h,configure.in: Check for <sys/time.h>. * gdk/win32: New directory (actually, been there for a while). * gtk/fnmatch.c: Include <glib.h> for G_DIR_SEPARATOR, WIN32 and NATIVE_WIN32, and use these. Always case fold on Win32. No backslashed escapes on native Win32. * gtk/{gtk.def,makefile.msc}: New files. * gtk/Makefile.am: Add above new files. * gtk/{gtkaccelgroup,gtkbindings}.c: Include <string.h> instead of <strings.h>. * gtk/{gtkcalendar,gtkitemfactory,gtkpreview,gtkrc}.c: Include config.h.

Use ABS() (from <glib.h>) instead of abs(). * gtk/gtkfilesel.c: Moved Win32-specific includes after inclusion of gtk (and thus glib) headers, so that WIN32 will be defined. With MS C, include <direct.h> for mkdir prototype. * gtk/gtkitemfactory.c (gtk_item_factory_callback_marshal): Add some casts, needed by MS C. * gtk/{gtklayout,gtkplug}.c: Merge in Win32 version (which isn't implemented). * gtk/gtkmain.c: Include gdk/gdkx.h for GDK_WINDOWING.

Use g_path_is_absolute.

Thu Jan 3 22:18:15 2002 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkdrawable-x11.c gdk/x11/gdkprivate-x11.h (_gdk_x11_have_render): Private function to tell if we have RENDER extension. * gdk/x11/gdkgc-x11.c (_gdk_x11_gc_get_fg_picture): Return None if we don't have RENDER extension. * gdk/x11/gdkpango-x11.c (gdk_pango_context_get): Don't use Xft unless we have render extension. * gdk/x11/gdkdrawable-x11.c (gdk_x11_drawable_get_picture): Handle missing render extension. * gdk/gdkdraw.c gdk/gdkdrawable.h gdk/gdkpixmap.c gdk/gdkwindow.c gdk/gdkinternals.h: Add a private copy_to_image() virtual function to the GdkDrawable vtable that extends get_image() to allow copying onto existing images. Make the default implementation of get_image() use this so that backends don't have to implement both. Add private wrapper _gdk_drawable_copy_to_image(). * gdk/x11/gdkimage-x11.c gdk/x11/gdkprivate-x11.c gdk/x11/gdkdrawable-x11.c (_gdk_x11_copy_to_image): Implement copy_to_image() semantics, speed up by using ShmPixmaps and XCopyArea when possible, XFlush() after ungrabbing the server, generally redo the logic once again. * gdk/gdkinternals.h gdk/x11/gdkimage-x11.c _gdk_windowing_bits_per_depth(): Function to convert from depth to bits-per-pixel. (We assume only one bpp per depth - X requires this.) * gdk/gdkinternals.h gdk/gdkrgb.c gdk/gdkimage.c: Move the GdkRGB scratch image code into a generic _gdk_image_get_scratch() chunk of code that we can use other places we need scratch images. * gdk/gdkimage.c gdk/x11/gdkimage.c gdk/gdkinternals.h: Add _gdk_image_new_for_depth() as the backend to _gdk_image_new() to allowing creating images with a depth and no visual. * gdk/gdkpixbuf-drawable.c: Fix so that getting parts of images not at 0,0 actually works. * gdk/gdkdrawable.h gdk/gdkinternals.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/gdkpixmap.c gdk/gdkpixbuf-render.c: - Add a new GdkDrawableClass vfunc _draw_pixbuf, and _gdk_draw_pixbuf() [ will be made public later ], to allow backends to accelerate drawing pixbufs. - Move the implementation of gdk_pixbuf_render_to_drawable_alpha() to be the default implementation. - Update docs for gdk_pixbuf_render_to_drawable_alpha(). - Optimize the default implementation by using _gdk_image_copy_to_pixmap() and scratch shared images, and special casing the compositing. * gdk/x11/gdkdrawable-x11.c: Accelerate _gdk_draw_pixbuf() with alpha using the RENDER extension. * gdk/gdkpixbuf-drawable.c (gdk_pixbuf_get_from_drawable): Optimize by _gdk_image_copy_to_pixmap() and scratch images. * tests/testrgb.c: Add test for speed of alpha composition, reduce the number of iterations since alpha composition can be a bit slow. * gdk/x11/gdkimage-x11.c gdk/gdkprivate-x11.h (_gdk_x11_image_get_shm_pixmap): Private function to get a ShmPixmap for an image, if possible.
