John Firebaugh	e11ab9699d	Avoid consecutive identical nodes when adding a midpoint ... Previously, adding a midpoint to an invalidly doubled-back segment (aba) resulted in a self-intersection with an invalid consecutive node (accba). Now a self-intersection is still produced, but with only one c node (acba). Refs #1296	2013-09-01 12:57:10 -07:00
John Firebaugh	b7894ceaf0	Calculate participating ways in AddMidpoint ... Due to differenced redraw, midpoint.ways was getting stale, so sometimes dragging a midpoint didn't add the new node to all ways. Better to calculate participating ways when needed. This also simplifies the code for adding a midpoint via double click. It does make filtering midpoints on redraw a bit more expensive, but a cursory profile didn't show it being a problem. Fixes #763.	2013-02-27 20:41:38 -08:00
