Commit b717de5153
changed the name of the "size" argument to
"virtualSize", as the "VirtualSize" field
was re-used for calculating the size of all
layers _not_ used by other images.
be20dc15af reverted
the change in calculation, but did not change
the argument name back to "size".
This changes the name back to its original
name, because since the introduction of the
content-addressable store in docker 1.10,
there no longer is a "virtual" size, so
"size" is a better name for this argument.
