This simplifies the process of constructing and encoding layout bitmaps. Instead of creating big integers and merging them, we can create a pre-sized bitmap and set positions within it. This also changes the encoding logic to allow larger layouts to be encoded inline. We would previously not encode a layout inline unless the size was less than the width of the data field. This is overly conservative. A layout can be encoded inline as long as: 1. The size fits within the size field. 2. All set bits in the bitmap fit into the data field.
