Updates since last meeting (on Monday, April 4, 2016): Scrolling
- Focus on root layer scrolling for now. The top most element, the layout view, (frame view contains layout view, both are scrollable areas. Frame view has special magic, plan is to have LayoutView handle scrolls using the standard ScrollableContainer logic. Been ongoing for awhile, skobes has done most of the work but has been pulled into other things. (szager) CSS Flexbox (cbiesinger)
- Spent way too much time on scrolling and will have to spent more time on scrolling. Still haven't found a good solution, trying to move scroll clamping to after the layout phase.
- Landed a few cleanup patches.
- Focus on other flexbox issues this week.
