Our background color propagation mechanism is designed to make rendering of translucent content more efficient by pre-blending against an opaque background. Currently this only works for text however, because images are not composited into their background even if the background color is opaque.
This diff precomposites network images with their background color when the background is opaque, allowing them to take advantage of this performance optimization.
I've also added some logic to correctly crop the downloaded image when the resizeMode is "cover" or "contain" - previously it was only correct for "stretch".

Test Plan: Run the UIExplorer "<ListView> - Paging" example with "color blended layers" enabled and observe that the images appear in green now, instead of red as they did before.
Summary:
ActivityIndicator was forwarding all of its props except `style` to the inner native view. This meant that onLayout would report a zero-sized frame that was relative to the wrapper view instead of the parent of the ActivityIndicator.
This diff adds `onLayout` to the wrapper view instead of the native view.
In general, all components that forward props need to be audited in this manner.

Test Plan: `<ActivityIndicator onLayout={...} />` reports the size of the spinner plus a position relative to its parent view.
Summary:
@vjeux and I were discussing this in irc an discovered that network gif images did not respond how they should to width, height or flex properties. Along the way I also noticed that the scale was not changing depending on the device. This PR fixes that, so now you can do `flex: 1` on a gif image to have it stretch to the whole screen. [Minimum reproducible example here](https://gist.github.com/brentvatne/f745377b0789162a28df) - try this without and then with the changes of this PR to see.

Summary:
This is a fix for #322
When setting a new image via the imageURL property, the new image
doesn't always replace the previous one when it is finished downloading
because the image view has a previously instated layer animation
on its contents. This cancels any animation prior to setting the new
contents to fix the issue.
