Shrink excess width from a set of item, by removing width from the larger items first. Set items Width to -1.0f to disable shrinking this item.

This function is merely here to free heap allocations.

For 32-bit and larger types, slider bounds are limited to half the natural type range. So e.g. an integer Slider between INT_MAX-10 and INT_MAX will f

Note: p_data, p_min and p_max are _pointers_ to a memory address holding the data. For a slider, they are all required. Read code of e.g. SliderFloat(

Small buttons fits within text without additional vertical spacing.

Using 'hover_visibility_delay' allows us to hide the highlight and mouse cursor for a short time, which can be convenient to reduce visual noise.

Those light colors are better suited with a thicker font than the default one + FrameBorder

Dockable windows uses Name/ID in the global namespace. Non-dockable items use the ID stack.

Order = visible order, not submission order! (which is tab->BeginOrder)

The *TabId fields are already set by the docking system _before_ the actual TabItem was created, so we clear them regardless.

Note: we may scroll to tab that are not selected! e.g. using keyboard arrow keys
