Fix the "ever-growing height" problem of Strip and Table demos (#3122)
* Fix the "ever-growing height" problem of Strip and Table Demos

Problem
-------

The height of "Table Demo" or "Strip Demo" floating window grows
when the demo app is interacted with. If 'Continuous' mode is enabled
in 'Backend' settings, the window grows irrespectively of user interaction.

Observations
------------

I noticed that [`area_content_ui.min_rect().max.y`][1] is increasing
monotonically with speed 0.5 px/frame.

I also noticed that commenting out `ui.add(crate::egui_github_link_file!());`
[statement][2] in `table_demo.rs` makes the problem disappear.

The "Fix"
---------

I added 0.5 to the height of the row with GitHub link.
This solved the problem.

Closes #3029.

Warning
-------

I failed to find the root cause of the problem.
I don't understand why this change makes the problem disappear.

* Document `Rect::size`

Other changes:

- `area.rs`: Use existing API.
- `table_demo.rs`: Remove unnecessary call.
