+Note: Issue #511 has reported that tile animation causes flickering/blinking in
+the iOS native browser. Forcing the browser to use hardware-accelerated
+animations fixed the issue, but #542 has reported that it also considerably
+slows down freehand drawing on iOS. If you're experiencing this and want to
+disable hardware-accelerated animations you can use the following rule in your
+CSS:
+
+    @media (-webkit-transform-3d) {
+        img.olTileImage {
+            -webkit-transform: none;
+        }
+    }
