	* app/file_new_dialog.c: New ui using code/ideas from Austin,
	Marco and Nick. The "size" frame is still a bit bloated but I
	didn't want to reduce it's functionality right now. It's closer to
	the result of the last discussion but not perfect yet...
	Added a dialog to confirm image sizes larger than the new

	* app/gimprc.[ch]: new rc variable max_new_image_size.

	* app/preferences_dialog.c: added the "max image size"

	* app/resize.c: an additional box lets the offset widget always...
