Some cleanup with Vector3(i)'s methods so that it is consistent with Vector2, for example it returns enums internally (GDScript still gets ints).

<brief_description>
|
|
Vector used for 2D math using integer coordinates.
|
|
</brief_description>
|
|
<description>
|
|
2-element structure that can be used to represent positions in 2D space or any other pair of numeric values.
|
|
It uses integer coordinates and is therefore preferable to [Vector2] when exact precision is required.
|
|
[b]Note:[/b] In a boolean context, a Vector2i will evaluate to [code]false[/code] if it's equal to [code]Vector2i(0, 0)[/code]. Otherwise, a Vector2i will always evaluate to [code]true[/code].

Gets the remainder of each component of the [Vector2i] with the components of the given [Vector2i]. This operation uses truncated division, which is often not desired as it does not work well with negative numbers. Consider using [method @GlobalScope.posmod] instead if you want to handle negative numbers.
