Added BlankEntity size modifiers

[exoego]

Closes #813

Not sure to add size override to transform(To|By) so skipped.

  def transformTo(newPosition: Point, newRotation: Radians, newScale: Vector2, newSize: Size): BlankEntity =
    this.copy(position = newPosition, rotation = newRotation, scale = newScale, size = newSize)

  def transformBy(positionDiff: Point, rotationDiff: Radians, scaleDiff: Vector2, sizeDiff: Size): BlankEntity =
    transformTo(position + positionDiff, rotation + rotationDiff, scale * scaleDiff, size = size * sizeDiff)

Perfect, thanks. 👍

Ah, sorry, just noticed this. resizeBy is addition of a relative amount, so * should be +.

[exoego]

Ok so only scale uses multiplication*

[davesmith00000]

Correct, yes. The use-case for resizeBy is "However big it is, I need it 10x10 pixels bigger".

I missed something...

Thanks! 😄
