ScreenElements do not tolerate 0 width and 0 height sizes

[eonarheim]

Steps to Reproduce

Create a ScreenElement without specifying a height or width

 let test = new ScreenElement()
 this.add(test)

Expected Result

This should create without issue.

Actual Result

Error is produced

Excalibur only supports convex polygon colliders and will not behave properly.Call PolygonCollider.triangulate() to build a new collider composed of smaller convex triangles

Environment

• browsers and versions: Chrome
• operating system: Windows
• Excalibur versions: latest main
• (anything else that may be relevant)

Current Workaround

Specify a non-zero width and height, then optionally remove the ColliderComponent if it's not desired or set it to ex.ColisionType.PreventCollision
