''Expand on the summary, if appropriate. A couple of sentences suffices to explain the goal, but the more details you can provide the better.''
Feature introduced two new classes - SmoothTable and TableView.
=== SmoothTable class ===
Model less implementation. The real widget consists of ''visible-columns'' * (''visible-rows'' + 2) identical widgets (constructor is passed to SmoothTable during creation) and while scrolling (by pixel); SmoothTable shifts these widgets.
=== TableView class ===
Just adds gtk.TreeModel support.

''Make sure to note here as well if this feature has been requested by a specific deployment, or if it has emerged from a bug report.''
Standard gtk components are not designed to be lazy. Third party widgets, I managed to find, uses scheme with renders (like gtk components), introduced component uses widgets instead (could have performance penalties, I guess, in common case but we don't have many rows in Journal view, so should be ok for us).
Benefits we have for such scheme:
* coding cells is more useful by using widgets than renders, we can reuse our existing custom widgets instead of coding sugarized cell renders
* in some cases it's hard to sugarize cells theme (we still have ugly progress bar for Journal entries), with new widget, we use just gtk.ProgressBar
