Just throw BadPicture instead of crashing. It's not currently a meaningful thing to do anyway, RenderSetPictureRectangles would error if you tried (which this patch changes to BadPicture as well for consistency). The problem with trying to do it is if the clip is specified as a pixmap then we try to convert it to a region, and ->BitmapToRegion requires a ScreenPtr, and source-only pictures don't have one. I can imagine a use for client clip on source-only pictures, so if we really wanted to allow this, probably the way forward is to always store the clip as a region internally, and when setting the clip _from_ a pixmap, look up BitmapToRegion relative to the pixmap not the picture. But since clearly nobody can be relying on it working...
