We must have googly eyes (new Game example)

[tjamaan]

Objective

• We must have googly eyes.
• Also it would be nice if there was an example of a desk toy application (like the old NEKO.EXE).

Solution

• Created an example with googly eyed Bevy logo under examples/games/desktoy.rs.

---

Changelog

• Added "Desk Toy" game example showcasing window transparency and hit test.

The generated examples/README.md is out of sync with the example metadata in Cargo.toml or the example readme template. Please run cargo run -p build-templated-pages -- update examples to update it, and commit the file change.

Updated as per comments and added more documentation.

I didn't turn the drag operation into a state machine since there is no cleaner way to test if there is a current drag operation while also storing the drag offset. E.g. there is no resource_equals equivalent that would ignore the inner enum values.
However I renamed DragOffset to DragOperation to make it clearer that this resource represents the drag operation.

In case it wasn't clear: I genuinely think we should include this. This is a nice well-scoped example demonstrating a new flavor of app, and I think that there's real pedagogical and marketing value to the fact that it's also extremely funny.

I think this should be named desk_toy.rs.

Nice! Testing this on Cinnamon, there are some problems with desktop mode though:

• Pressing space triggers the toggle every frame. This isn't this PR's fault though; looks like Opening a Window on keyboard_input.just_pressed makes it trigger again #12273
• Clicking the logo doesn't focus the window (also not this PR's fault)
• the window size stays the same instead of being full-screened, so I can only move the logo in the window's bounds

I tried making the primary window fullscreen but macOS puts it into its own workspace (even if it’s borderless).

Very fun! Definitely on board, especially with tweaks to the velocity and decay as mentioned in the comments above.

@tjamaan ping me once you've tweaked the physics and I'll merge this in :)

cargo fmt is failing :)

cargo fmt is failing :)

I have automatic format on save configured and I also ran cargo fmt manually. Can you share the error?

e: It appears that was because it checked before I fixed the references to the renamed file.

@alice-i-cecile I've toned down the bounciness, cleaned up the code as suggested, and renamed the file to desk_toy.rs
