Lazily compute layout->log_attrs
Submitted by Morten Welinder
Link to original bug (#123646)
Description
Displaying a list (treeview) with just 100 lines each consisting of 10000 x's and nothing else takes ~5s. This is with today's cvs.
See bug 123538 [Gnumeric text import with long lines is slow]. See bug 114943 [no way to set GtkCellRendererText to single-paragraph mode].
