+#X text 171 448 @outer does the same two-input operation between every
+possible pair of the left-side grid and the right side grid. @inner
+treats both input grids like @fold does \, then does a @outer on the
+other dimensions \, such that every two-input operation is like a @fold.
+this is a very powerful operation that can be used to do rotations
+\, rgb->yuv \, color conversions \, etc.;
