+Subject: [PATCH] Fix bilinear filter computation in wide pipeline
+
+The recently introduced wide pipeline for filters has a typo which
+causes it to improperly compute bilinear interpolation positions,
+causing various glitches when enabled.
+
+This patch uses the proper computation for bilinear interpolation in the
+wide pipeline.  It also makes related `if` statements conformant to the
+CODING_STYLE:
+
+* If a substatement spans multiple lines, then there must be braces
+  around it.
+
+* If one substatement of an if statement has braces, then the other
+  must too.
