[BUG] SKMatrix.MapRect method standardizes the output rectangle.

[TormodS]

Description

Due to many various libraries/formats from legacy systems, we deal with various coordinate systems.
The "Top" of an SKRect artifact is not always the smalles Y number" and the Y axis does not always decrease when moving up on the screen.
Similar on the X axis. What the user perceives as the "Left" of a screen artifact may along the way have been higher X coordinate due to the format that it was persisted in.

A use case for me is to draw in any technology specific coordinate system and have a SKMatrix map the points to their corresponding output coordinates.

Having quirks like this inside the library affects the whole concept of matrices since operation1 and operation2 done separately will no longer equal their concatenation if operation1 decides to standardize the intermediate result.

Code

var inputRect = new SKRect();

inputRect.Left =25; 
inputRect.Right = 15;
inputRect.Bottom = 2;
inputRect.Top = 10;
// For simplicity, I have entered the described case here. But this test should be for all variations of inputRect.
var resultRect = SKMatrix.CreateIdentity().MapRect(inputRect);

Assert.AreEqual(inputRect.Right,resultRect.Right);
Assert.AreEqual(inputRect.Left,resultRect.Left);
Assert.AreEqual(inputRect.Top,resultRect.Top);
Assert.AreEqual(inputRect.Bottom,resultRect.Bottom);

Expected Behavior

The resultRectangle.Left == inputRectangle.Left
The resultRectangle.Right == inputRectangle.Right
The resultRectangle.Top == inputRectangle.Top
The resultRectangle.Bottom == inputRectangle.Bottom

I expect to use .Standardized property or similarif I want X/Y axis "corrected" (/flipped) in the output rectangle.

Actual Behavior

The resultRectangle.Left == inputRectangle.Right
The resultRectangle.Right == inputRectangle.Left
The resultRectangle.Top == inputRectangle.Bottom
The resultRectangle.Bottom == inputRectangle.Top
