	* macosx/tkMacOSXXStubs.c:
	* xlib/ximage.c: fixed MacOSX XGetImage/XPutImage and related
	functions to deal properly with XImages copied from screen.
	* generic/tkCanvPs.c (TkImageGetColor): MacOSX fix.
	* generic/tkImgPhoto.c (ImgPhotoDisplay): enabled alpha blending
	for images with partial transparency on MacOSX.
