* [License] Simplify the Texture license to be pure Apache 2 (removing ASDK-Licenses) With permission of the Facebook Open Source team, we are simplifying the Texture license so that clients can rely on the Apache 2 terms that most of Texture is already covered by. This means that code originally forked from AsyncDisplayKit will be re-licensed from "BSD 3-clause + PATENTS v2" to Apache 2 without a PATENTS file. After getting confirmation that the updates to these core files look good, we'll propagate this new license header to all files (in this same PR) and get sign-off from all parties before landing. * [License] Update all Texture source files to be pure Apache 2. * Changelog entry for Apache 2 license update. * Revert "[License] Update all Texture source files to be pure Apache 2." This reverts commit ffa0fbbba9717d871dd16c4b07539f2f8208fc2b. * [License] Update all Texture source files to be pure Apache 2, maintaining copyrights. * [License] Update CONTRIBUTING, README, Podspec & Dangerfile.

/**
|
|
A layout spec that wraps another layoutElement child, applying insets around it.
|
|
|
|
If the child has a size specified as a fraction, the fraction is resolved against this spec's parent
|
|
size **after** applying insets.
|
|
|
|
@example ASOuterLayoutSpec contains an ASInsetLayoutSpec with an ASInnerLayoutSpec. Suppose that:
|
|
- ASOuterLayoutSpec is 200pt wide.
|
|
- ASInnerLayoutSpec specifies its width as 100%.
|
|
- The ASInsetLayoutSpec has insets of 10pt on every side.
|
|
ASInnerLayoutSpec will have size 180pt, not 200pt, because it receives a parent size that has been adjusted for insets.
|
|
|
|
If you're familiar with CSS: ASInsetLayoutSpec's child behaves similarly to "box-sizing: border-box".
|
|
|
|
An infinite inset is resolved as an inset equal to all remaining space after applying the other insets and child size.
|
|
@example An ASInsetLayoutSpec with an infinite left inset and 10px for all other edges will position it's child 10px from the right edge.
