Snap feature wasn't working for deep regions in certain use
cases.
* Enhancement: new "scale_and_snap" methods
These methods allow scaling and snapping of layouts. Scaling
is supported by a rational factor. After scaling, snapping can
be applied to an integer grid. There are two incarnations.
Region#scale_and_snap (or Region#scaled_and_snapped): this is
a flat implementation which allows anisotropic scaling/snapping
as well.
And there is Layout#scale_and_snap which is a fully
hierarchical scale-and-snap feature. The latter does not support
anisotropic scaling/snapping, but works hierarchically without
opening gaps. It operates on a top cell and on all layers.
* Enhancement: new Region#pull_* methods and DRC features
