FlxSprites with a negative scale stop rendering when reaching the edge of a camera

[mayo78]

• Haxe version: 4.2.5
• Flixel version: 5.3.1
• OpenFL version: 9.2.1
• Lime version: 8.0.1
• Affected targets: probably all?

Code snippet reproducing the issue:

package;

import flixel.util.FlxColor;
import flixel.FlxG;
import flixel.FlxSprite;
import flixel.FlxState;

//press a to swap from an x scale of 1 and -1, red is 1 blue is -1

class PlayState extends FlxState
{
	var hi:FlxSprite;
	override public function create()
	{
		hi = new FlxSprite().makeGraphic(100, 100, FlxColor.WHITE);
		hi.color = FlxColor.RED;
		add(hi);
		super.create();
	}

	override public function update(elapsed:Float)
	{
		hi.setPosition(FlxG.mouse.x, FlxG.mouse.y);
		if(FlxG.keys.justPressed.A) {
			hi.scale.x *= -1;
			hi.color = (hi.scale.x == -1) ? FlxColor.BLUE : FlxColor.RED;
			hi.updateHitbox();	
		}
		super.update(elapsed);
	}
}

Observed behavior: the sprite stops rendering at the edge of the camera when it should be visible

Expected behavior: the sprite stops rendering when it leaves the cameras area

Scale should not be negative, if you want to invert a sprite, use the flipX and flipY fields

Ill see if this can be handled better, but negative scale may cause other issues elsewhere, and should really be avoided
