+Subject: [PATCH] Initialise residual when less than the transform width is
+ visible
+
+The input stride for forward transforms did not match the output
+stride of residual computation in this case. Extend the residual
+stride to the transform width and zero the non-visible portion.
+Fixes #2662. Fixes #2757.
