+/* Haswell border color is a bit of a disaster.  Float and unorm formats use a
+ * straightforward 32-bit float color in the first 64 bytes.  Instead of using
+ * a nice float/integer union like Gen8+, Haswell specifies the integer border
+ * color as a separate entry /after/ the float color.  The layout of this entry
+ * also depends on the format's bpp (with extra hacks for RG32), and overlaps.
+ *
+ * Since we don't know the format/bpp, we can't make any of the border colors
+ * containing '1' work for all formats, as it would be in the wrong place for
+ * some of them.  We opt to make 32-bit integers work as this seems like the
+ * most common option.  Fortunately, transparent black works regardless, as
+ * all zeroes is the same in every bit-size.
