Allowing the user to call NewFrame() multiple times without calling Render()

Note that this is never a good idea. But, allowing it reduce confusion
in the initial stage of setup.

ISSUES AND TODO-LIST
- misc: allow user to call NewFrame() multiple times without a render.
- misc: merge ImVec4 / ImGuiAabb, they are essentially duplicate containers
- window: autofit is losing its purpose when user relies on any dynamic layout (window width multiplier, column). maybe just discard autofit?
- window: support horizontal scroll
@ -148,6 +147,7 @@
- input: keyboard: full keyboard navigation and focus.
- input: support trackpad style scrolling & slider edit.
- misc: not thread-safe
- misc: double-clicking on title bar to minimize isn't consistent, perhaps move to single-click on left-most collapse icon?
- optimisation/render: use indexed rendering
- optimisation/render: move clip-rect to vertex data? would allow merging all commands
- optimisation/render: merge command-list of all windows into one command-list?
