==Pan/Zoom Jank==
==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.
