Bring drawRect back

[luanpotter]

@erickzanardo convinced me we should have two overloads for the render method (the current one and the one that takes a Rect)

[spydon]

Can you explain why it is needed?

[erickzanardo]

Rect is a really useful class, I have caught myself creating rects to do some operation and then turning then back to Vector2 to render, so this is a good utility method.

[spydon]

Could we add those operations on Vector2, or are there operations involving code we are not in control of?

[erickzanardo]

That is a good question, we sure could try enhance Vector2 and see how it goes, the problem for me is that Rect and Vector2 are not equivalent, like, Rect has a position and a size, a Vector2, only the position.

I will list some of the methods that I commonly use on Rect and we can try to think if that could be applied to Vector2:

• inflate
• deflate
• shift
• translate
• fromCenterPoint (constructor)

We could also maybe add some extensions on canvas for vector2, like a drawVector2Rect(pos, size, paint), that could help as well.
