 ## Background Image via Nesting

 ## Static Assets
 
-In the course of a project you add and remove images and in many instances, you end up shipping images you are not using anymore in the app. In order to fight this, we need to find a way to know statically which images are being used in the app. To do that, we introduced a marker called `ix`. The only allowed way to refer to an image in the bundle is to literally write `ix('name-of-the-asset')` in the source.

-On the infrastructure side, the reason is that it allows to attach metadata to this object. For example if you are using `ix`, then we add a `isStored` attribute to flag it as a local file (don't rely on this fact, it's likely to change in the future!). This is also future proofing, for example we may want to support sprites at some point, instead of outputting `{uri: ...}`, we can output `{uri: ..., crop: {left: 10, top: 50, width: 20, height: 40}}` and transparently support spriting on all the existing call sites.

 On the user side, this lets you annotate the object with useful attributes such as the dimension of the image in order to compute the size it's going to be displayed in. Feel free to use it as your data structure to store more information about your image.

The notable difference from web is the security model: you can read from arbitrary websites on the internet, there isn't no concept of [CORS](http://en.wikipedia.org/wiki/Cross-origin_resource_sharing).

 ## Pixel Grid Snapping
 
-In iOS, you can specify positions and dimensions for elements with arbitrary precision, for example 29.674825. But, ultimately the physical display only have a fixed number of pixels, for example 640×960 for iphone 4 or 750×1334 for iphone 6. iOS tries to be as faithful as possible to the user value by spreading one original pixel into multiple ones to be trick the eye. The downside of this technique is that it makes the resulting element look blurry.

 In practice, we found out that developers do not want this feature and they have to work around it by doing manual rounding in order to avoid having blurry elements. In React Native, we are rounding all the pixels automatically.
