// Cursor / Layout
// Layout cursor positioning
// - By "cursor" we mean the current output position.
// - The typical widget behavior is to output themselves at the current cursor position, then move the cursor one line down.
// - You can call SameLine() between widgets to undo the last carriage return and output at the right of the preceding widget.
// - Attention! We currently have inconsistencies between window-local and absolute positions we will aim to fix with future API:
// Window-local coordinates: SameLine(), GetCursorPos(), SetCursorPos(), GetCursorStartPos(), GetContentRegionMax(), GetWindowContentRegion*(), PushTextWrapPos()
// Absolute coordinate: GetCursorScreenPos(), SetCursorScreenPos(), all ImDrawList:: functions.
// - Absolute coordinate: GetCursorScreenPos(), SetCursorScreenPos(), all ImDrawList:: functions. -> this is the preferred way forward.
// - Window-local coordinates: SameLine(), GetCursorPos(), SetCursorPos(), GetCursorStartPos(), GetContentRegionMax(), GetWindowContentRegion*(), PushTextWrapPos()
// - GetCursorScreenPos() = GetCursorPos() + GetWindowPos(). GetWindowPos() is almost only ever useful to convert from window-local to absolute coordinates.
