manifold:\n\n- We needed to traverse the whole hist_entry rb_tree to add each entry +\n callchains beforehand.\n\n- No control over the colors used for each row\n\nSo a new tree widget, based mostly on slang, was written.\n\nIt extends the ui_browser class already used for annotate to allow the\nuser to fold/unfold branches in the callchains tree, using extra fields\nin the symbol_map class that is embedded in hist_entry and\ncallchain_node instances to store the folding state and when changing\nthis state calculates the number of rows that are produced when showing\na particular hist_entry instance.\n\nThis greatly speeds up browsing as we don\u0027t have to upfront touch all\nthe entries and only calculate callchain related operations when some\ncallchain branch is actually unfolded.\n\nThe memory footprint is also reduced as the data structure is not\nduplicated, just some extra fields for controling callchain state and to\nsimplify the process of seeking thru entries
