Lucas Meurer 0ef57d5a1d Fix `ui.response().interact(Sense::click())` being flakey (#7713)
This fixes calls to `ui.response().interact(Sense::click())` being
flakey. Since egui checks widget interactions at the beginning of the
frame, based on the responses from last frame, we need to ensure that we
always call `create_widget` on `interact` calls, otherwise there can be
a feedback loop where the `Sense` egui acts on flips back and forth
between frames.

Without the fix in `interact`, both the asserts in the new test fail.

Here is a video where I experienced the bug, showing the sense switching
every frame. Every other click would fail to be detected.

Also note, usually it's better to use `UiBuilder::sense()` to give a Ui
some sense, but sometimes you don't have the flexibility, e.g. in a `Ui`
callback from some code external to your project.

GUI implementation

This is the core library crate egui. It is fully platform independent without any backend. You give the egui library input each frame (mouse pos etc), and it outputs a triangle mesh for you to paint.
