Prototype: Scary Vec2s and Nice Sprites

[pushfoo]

TL;DR: Proof we can Vec2 all *Sprite without destroying the universe!

[ Obligatory Skrillex Noises ]

Note

The remaining pyright issues belong in #2183

How to try it

In your Arcade clone

1. git checkout upstream/scary-vecs-and-nice-sprites or however you have your remotes instealled
2. pip install -I -e .[dev]
   • This is very important
   • Do it every time you switch to or back from this branch
3. Proceed as normal, see what breaks

In your Project

For the latest unstable version:
arcade@git+https://github.com/pythonarcade/arcade/arcade.git@scary-vecs-and-nice-sprites#egg=arcade

You can also pin specific commits using a zipball link, but that's more convoluted.

Changes

1. For BasicSprite and subclasses, the following are now Vec2:
   • .size is now a Vec2 backed by ._size
   • .position is now a Vec2
   • .scale is now a Vec2
2. _width and _height are now compatibility properties for any subclasses we missed
3. Dependent functions are mostly updated

What's not changed

Anything outside the sprites really. Seriously. There's a sound tweak to get it to pass and run, but otherwise, not even tests.

Current Code Quality

Already done:

• Pyglet2.1dev$VERSION updates #2226
• Name scale properties on Sprites to things that make sense #2021

Sprites pass:

• pytest tests/unit
• pyright
• ./make./py format + ruff check arcade

Otherwise, no guarantees:

Follow-up Work

• Verify the tests cover what they should
• Perf tests and metrics to decide how to proceed with:

Right, I need to figure out the zipballs since it's dependent on pyglet/pyglet#1154

[pushfoo]

Zipball's fixed, but the other pyright issues belong in #2183.

I've dropped the zipball commits during rebase onto development. We're on pyglet==2.1dev4 now.
