/* The gradient pattern creates two horizontal gray gradients, split
* into two halves. The top half has 10bpc precision, the bottom half
* has 8bpc precision. When using with a 10bpc fb format, there are 3
* 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.
