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.
