* [BottomSheet] Add BUILD file for kokoro + bazel support.
I will be sending out a variety of pull requests soon to the bottom sheet. Adding the component to kokoro will let the PRs land more quickly.
* Remove unused load statements.
Rather than potentially returning a CGRectNull and causing UIKit crashes
if it's assigned to a view's frame or bounds, treat a scale of 0 as a
scale of 1.
Closes#2044
Although it is possible to currently align a CGRect (frame) to a
pixel-aligned bounding rectangle, in some cases manipulating the frame
is neither possible nor desirable (such as when the transform is not the
identity). Adding two new methods to support rounding a CGPoint to a
pixel and aligning the center point of a UIVIew given its bounds.
Adding a new function to realign a CGRect (frame) to pixel boundaries
based on the screen scale. After a review of the catalog, I'm updating
the areas where I found misaligned frames.
Closes#1723
