The +Flipbook Size+ setting changed from the _Vector2 type_ to "Flipbook" which is a _Vector2 int _type.

Vector2 cannot be wired to Flipbook property as no conversion/cast is handled. This can create an upgrade issue with VFX that were using Wired Vector2 property to the Flipbook setting.

*Reproduction Step:*
