I had wanted to use MAYBE_ here, but for whatever reason that doesn't work well
with TEST_P. No idea why.

 TEST_P(DisplayManagerTest, TestDeviceScaleOnlyChange) {
-  if (!SupportsHostWindowResize())
-    return;

   UpdateDisplay("1000x600");
   aura::WindowTreeHost* host = Shell::GetPrimaryRootWindow()->GetHost();
   EXPECT_EQ(1, host->compositor()->device_scale_factor());
   EXPECT_EQ("1000x600",
             Shell::GetPrimaryRootWindow()->bounds().size().ToString());
   EXPECT_EQ("1 0 0", GetCountSummary());
 
   UpdateDisplay("1000x600*2");
   EXPECT_EQ(2, host->compositor()->device_scale_factor());
   EXPECT_EQ("2 0 0", GetCountSummary());
   EXPECT_EQ("500x300",
             Shell::GetPrimaryRootWindow()->bounds().size().ToString());
 }
