Tim Edwards	2914286921	Resolved a tricky issue with the crosshair drawing. The crosshair routine was erasing and redrawing in one step, which ignored the possibility of having to erase from one window and redraw in another if the cursor moved focus from one window to another. This led to crosshairs being improperly drawn and erased when multiple windows were present, if the windows had different cells loaded.	2018-10-17 10:30:55 -04:00
Tim Edwards	8ca2db78a2	Corrected failure to update root box and crosshair position when rescaling the internal units. The former in particular can cause problems when moving the root box and importing cells from a script (same change as made to magic-8.1).	2017-09-26 14:09:35 -04:00
Tim Edwards	3108e5f18c	Found that the crosshair function was wasting compute cycles by drawing out-of-bounds when the crosshair was turned off rather than just not drawing it.	2017-09-15 22:20:00 -04:00
