* macosx/tkMacOSXXStubs.c (XCreateImage, DestroyImage): correct XImage
bytes_per_line/bitmap_pad calculations and endianness setting; free image data and XImage structure at destruction; formatting cleanup. * macosx/tkMacOSXDialog.c (NavServicesGetFile): disable app-modal sheet variant of nav dialog on OS versions where it causes problems.
