Known direct subclasses

AwaitPointerEventScope, CacheDrawScope, DrawScope, GraphicsLayerScope, InjectionScope, IntrinsicMeasureScope, MeasureScope, PointerInputScope, PressGestureScope, RulerScope

`AwaitPointerEventScope`	Receiver scope for awaiting pointer events in a call to `PointerInputScope.awaitPointerEventScope`.
`CacheDrawScope`	Handle to a drawing environment that enables caching of content based on the resolved size.
`DrawScope`	Creates a scoped drawing environment with the provided `Canvas`.
`GraphicsLayerScope`	A scope which can be used to define the effects to apply for the content, such as scaling (`scaleX`, `scaleY`), rotation (`rotationX`, `rotationY`, `rotationZ`), opacity (`alpha`), shadow (`shadowElevation`, `shape`), and clipping (`clip`, `shape`).
`InjectionScope`	The receiver scope of all input injection lambdas offered in `ui-test`, such as `performTouchInput` and `performMouseInput`.
`IntrinsicMeasureScope`	The receiver scope of a layout's intrinsic measurements lambdas.
`MeasureScope`	The receiver scope of a layout's measure lambda.
`PointerInputScope`	Receiver scope for `Modifier.pointerInput` that permits `handling pointer input`.
`PressGestureScope`	Receiver scope for `detectTapGestures`'s `onPress` lambda.
`RulerScope`	A scope used in `MeasureScope.layout` for the `rulers` parameter to allow a layout to define `Ruler` values for children.

Known indirect subclasses

ApproachIntrinsicMeasureScope, ApproachMeasureScope, CanvasDrawScope, ContentDrawScope, DragAndDropSourceScope, KeyInjectionScope, LazyLayoutMeasureScope, MeasureScope, MouseInjectionScope, MultiModalInjectionScope, RotaryInjectionScope, SubcomposeMeasureScope, TouchInjectionScope

`ApproachIntrinsicMeasureScope`	The receiver scope of a layout's intrinsic approach measurements lambdas.
`ApproachMeasureScope`	`ApproachMeasureScope` provides access to lookahead results to allow `ApproachLayoutModifierNode` to leverage lookahead results to define how measurements and placements approach their destination.
`CanvasDrawScope`	Implementation of `DrawScope` that issues drawing commands into the specified canvas and bounds via `CanvasDrawScope.draw`
`ContentDrawScope`	Receiver scope for drawing content into a layout, where the content can be drawn between other canvas operations.
`DragAndDropSourceScope`	This interface is deprecated. Replaced by a callback for obtain a transfer data,start detection is performed by Compose itself
`KeyInjectionScope`	The receiver scope of the key input injection lambda from `performKeyInput`.
`LazyLayoutMeasureScope`	The receiver scope of a `LazyLayout`'s measure lambda.
`MeasureScope`	The receiver scope of a layout's measure lambda.
`MouseInjectionScope`	The receiver scope of the mouse input injection lambda from `performMouseInput`.
`MultiModalInjectionScope`	The receiver scope of the multi-modal input injection lambda from `performMultiModalInput`.
`RotaryInjectionScope`	The receiver scope of rotary input injection lambda from `performRotaryScrollInput`.
`SubcomposeMeasureScope`	The receiver scope of a `SubcomposeLayout`'s measure lambda which adds ability to dynamically subcompose a content during the measuring on top of the features provided by `MeasureScope`.
`TouchInjectionScope`	The receiver scope of the touch input injection lambda from `performTouchInput`.

A density of the screen. Used for the conversions between pixels, Dp, Int and TextUnit.
