ScaleStrategy (MultimediaLib 2018.2 API)

```
public class ScaleStrategy
extends java.lang.Object
```
Influences how and if the renderer scales graphics when the canvas and the screen are not of the same size. This is especially relevant if the application will be used on devices with different screen sizes and aspect ratios.

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`int`	`convertToCanvasX(Rect screen, int screenX)`
`int`	`convertToCanvasY(Rect screen, int screenY)`
`int`	`convertToScreenX(Rect screen, int canvasX)`
`int`	`convertToScreenY(Rect screen, int canvasY)`
`static ScaleStrategy`	`fixed(int canvasWidth, int canvasHeight)` Does not scale the canvas, keeping it at the specified size regardless of the size of the screen.
`static ScaleStrategy`	`flexible(int initialCanvasWidth, int initialCanvasHeight)` Performs no scaling so that the canvas size always matches the screen size.
`Rect`	`getCanvasBounds(Rect screen)` Returns the size and position of the canvas when applying this scale strategy to the specified screen.
`int`	`getCanvasHeight(Rect screen)` Returns the (non-scaled) height of the canvas used by this scale strategy.
`int`	`getCanvasWidth(Rect screen)` Returns the (non-scaled) width of the canvas used by this scale strategy.
`Rect`	`getPreferredCanvasBounds()`
`float`	`getScaleFactorX(Rect screen)`
`float`	`getScaleFactorY(Rect screen)`
`static ScaleStrategy`	`proportional(int canvasWidth, int canvasHeight)` Scales the canvas to match the screen size, but without changing its aspect ratio.
`static ScaleStrategy`	`smart(int canvasWidth, int canvasHeight)` Scales the canvas to match the screen size.
`static ScaleStrategy`	`stretch(int canvasWidth, int canvasHeight)` Stretches the canvas to match the screen size.
