Subject: [PATCH] ludic.ui: a pooled node's reset lets go of its wrapped lines
 instead of clearing them - they are the memo's list (ly_wrap), shared by
 every node with that text, so a text that wraps vanished from the third frame
 on, in the game as in ui-preview; smoke.txt holds four frames of it
