+/* The gradient pattern creates two horizontal gray gradients, split

+ * possible outcomes:
+ *
+ * - Pixel data is encoded as 8bpc to the display, no dithering. This
+ * would lead to the top and bottom halves looking identical.
+ *
+ * - Pixel data is encoded as 8bpc to the display, with dithering. This
+ * would lead to there being a visible difference between the two halves,
+ * but the top half would look a little speck-y due to the dithering.
+ *
+ * - Pixel data is encoded at 10bpc+ to the display (which implies
+ * the display is able to show this level of depth). This should
+ * lead to the top half being a very clean gradient, and visibly different
+ * from the bottom half.
+ *
+ * Once we support additional fb formats, this approach could be extended
+ * to distinguish even higher bpc precisions.
+ *
+ * Note that due to practical size considerations, for the screens
+ * where this matters, the pattern actually emits stripes 2-pixels
+ * wide for each gradient color. Otherwise the difference may be a bit
+ * hard to notice.
