Popups: fix to allow child popups to be opened from a normal window without an intermediate popup window.

Selectable: using window->WindowPadding() to work within non-padded child windows

Window: fixed auto-fit calculation mismatch of whether a scrollbar will be added by maximum height clamping. ...

Also honor NoScrollBar in the case of height clamping, not adding extra
horizontal space.

Style editor: fixed slider for indent spacing.

Window: fixed child window sizing lag + minimum size clamping lag

Popups: child popups (menus) hidden on their first frame the same way as regular popup

Popups: made OpenPopup()/close loops reclaim focus and update popup position. It is generally a mistake but it's now more easy to understand

ImVector: tweak growth strategy

Metrics: do not count free(NULL) calls. Settings: contiguous allocations for ImGuiIniData.

Metrics: metrics window shows popups list

Examples: Console: example uses standard malloc/free, makes more sense as a copy & pastable example

Added IO.MetricsAllocs counter (number of memory allocations

Popups: fixed child windows within popups vs handling of sub menus. Added examples.

Popups: identifying popups by their id to avoid conflict when recycling popup durnig same same (CloseCurrentPopup followed by Open+Begin)
