 ==Pan/Zoom Jank==
-#page load?
+* Our only known source of jank is texture upload.
-#Zoom in (dbl tap, pinch 2 zoom)
+* Currently we should never jank during zoom because we do not do any uploads then.
-#Zoom out (dbl tap, pinch 2 zoom)
+* Kats recently started drawing on double tap out so it's possible we introduced some jank during that operation.
-#Scrolling
+If we need to, it should be possible to postpone the upload of until the end of zoom operation, or use another technique to bound the time we spend uploading.
