sc tiled editing: Use the LogicMapMode even for mouse positions.

Instead of using whatever MapMode value that was used the last time for
rendering the tile, set it to something predictable when counting the mouse
clicks (100% zoom), and use the value consistently in Calc via
GetDrawMapMode().

This fixes clicking the shapes in various zoom levels.
