* Hit tests don't lay out dashes: moving the mouse over a block stays smooth (#1285) Every mouse move hit-tests the block references under the cursor, and hit_polylines built them with a full-detail display list, one primitive per dash. A fine pattern on long lines in a block inserted at 0.001 made millions of dashes per move. Options::linetypes off draws every line whole and continuous, and hit_polylines uses it for blocks, dimensions and multileaders. A dashed line in a block is now hit across its gaps, as one outside a block already was.
