FIXME: This may incur a round-trip (if the end user got their data from a float4) but eventually we aim to store the in-flight colors as ImU32

We don't use g.FontSize because the window may be != g.CurrentWidow.

Render an arrow aimed to be aligned with text (p_min is a position in the same space text would be positioned). To e.g. denote expanded/collapsed stat

Render an arrow. 'pos' is position of the arrow tip. half_sz.x is length from base to tip. half_sz.y is length on each side.

Helper for ColorPicker4() NB: This is rather brittle and will show artifact when rounding this enabled if rounded corners overlap multiple cells. Call

FIXME: Cleanup and move code to ImDrawList.

Internal ImGui functions to render text RenderText***() functions calls ImDrawList::AddText() calls ImBitmapFont::RenderText()

Call registered handlers (e.g. SettingsHandlerWindow_WriteAll() + custom handlers) to write their stuff into a text buffer

FIXME-OBSOLETE: May need to obsolete/cleanup those helpers.

Allow last item to be overlapped by a subsequent item. Both may be activated during the same frame before the later one takes priority.
