(Fixed missing sinking property in objects list for multipart objects
with a part completely below the printbed):

It was not possible to slice an object with some part completely below
the print bed. The BuildVolume collision check newly supports
a "completely below print bed" return status,
Model evaluates this "completely below print bed status" allowing
objects with some volumes completely below the print bed to print.
