waffle f738fbd4f8 gpui: Disable rounding in the layout engine (#31836) ...

Rounding broke (among other things, probably) pixel-perfect image
rendering with non-power-of-two scaling factor.

An example which reproduces the problem can be found
[here](https://github.com/WaffleLapkin/gpui_taffy_rounding_whyyyyy).

How it looks with `gpui` from `main`:

How it looks with this patch:

Both screenshots are made on kde+wayland with magnification using kde's
built-in magnification (`Meta`+`+`, `Meta`+`-`). Note that screenshot
apps have a high chance of lying 🙃

The image itself is 400 by 300 pixels of red/green checkerboard pattern
made specifically to exaggerate scaling issues.
