A selection of several parts is moved by ElementPrimitiveDecorator, which snapped to a fixed 1-unit step at every zoom. That is the "selection is big" half of #112: below 100 % one part landed on the 10 grid but a multi-part selection did not, and at 100-400 % it ignored the grid too. It now snaps to the editor's current grid, as a single part does; Ctrl still gives the fine 1-unit step. Resizing and arrow-key moves are unchanged. Also from review: add rows just below each zoom threshold to tst_elementviewgrid (each catches a moved threshold the old rows missed), and use one grid_step in drawBackground() instead of identical x/y copies.
