Change GDK_WINDOWING_WIN32 usage to #ifdef also here.

1999-10-03  Tor Lillqvist  <tml@iki.fi>

* gdk/gdkimage.h gdk/gdkpixmap.h: Change GDK_WINDOWING_WIN32 usage
to #ifdef also here.

* gdk/win32/*.h gdk/win32/*.c: Make corresponding changes as those
Owen did to the X11 backend.

* gdk/win32/gdkdraw.c (gdk_draw_pixmap): Fix it again, don't use
ScrollWindowEx when blitting inside a window, it can't be correct
in the general case.

* gdk/win32/gdkevents.c: Don't handle WM_SIZING, handling
WM_GETMINMAXINFO is easier.

* gdk/win32/gdkimage.c (gdk_image_new): Create new image with
depth equal to the bitspixel value, not the visual's depth.

* gdk/win32/gdkvisual.c (gdk_visual_init): Set the visual's depth
to 24 even if the bitspixel value is 32.

* gdk/gdkrgb.c (gdk_rgb_select_conv): After the above change, no
need to check for depth==32 when bpp==32, depth will always be 24.
