From 162cbde1dd62710a506d86bce2e57e26dad3d801 Mon Sep 17 00:00:00 2001 From: Nikita Yushchenko Date: Thu, 12 Oct 2017 20:52:28 +0300 Subject: fbtest: add gradients pattern This pattern draws red, green, blue, and white color gradients, together with 3 anchor rectangles in corners. To be used with automated screen testing via computer vision methods.
