- font: fix AddRemapChar() to work before font has been built.
- font: (api breaking) removed "TTF" from symbol names. also because it now supports OTF.
- nav: integrate navigation branch into master. (#787)
- nav: SetItemDefaultFocus() level of priority, so widget like Selectable when inside a popup could claim a low-priority default focus on the first selected iem
- nav: allow input system to be be more tolerant of io.DeltaTime=0.0f
- nav: Left within a tree node block as a fallback.
- nav: Esc on a flattened child
- nav: ESC on a flattened child
- nav: Left within a tree node block as a fallback (ImGuiTreeNodeFlags_NavLeftJumpsBackHere by default?)
- nav: menus: pressing left-right on a vertically clipped menu bar tends to jump to the collapse/close buttons.
- nav: menus: allow pressing Menu to leave a sub-menu.
- nav: integrate/design keyboard controls.
- nav: simulate right-click or context activation? (SHIFT+F10)
- nav: tabs should go through most/all widgets (in submission order?).
- nav: when CTRL-Tab/windowing is active, the HoveredWindow detection doesn't take account of the window display re-ordering.
