* Closes https://github.com/emilk/egui/issues/4241
I would love some more testers of this.
I'm not sure if we really need the round-to-even code, but I'm hesitant
to out-right revert https://github.com/emilk/egui/pull/151 when I cannot
reproduce its problem. Keeping it seems quite safe though.

# Testing
Checkout the branch and run:
* `./scripts/start_server.sh`
* `./scripts/build_demo_web.sh` and then open
`http://localhost:8888/index.html#Rendering`
* `./scripts/build_demo_web.sh --wgpu` and then open
`http://localhost:8888/index.html#Rendering`
Check the "Rendering test" that the squares in the pixel alignment test
are perfectly sharp, like this:

If it looks something like this, something is WRONG:

Please try it on different zoom levels in different browsers, and if
possible on different monitors with different native dpi scaling. Report
back the results!
### Mac
I have tested on a high-DPI Mac:
* Chromium (Brave): ✅ Can reproduce problem on `master`, and it's now
fixed
* Firefox: ✅ Can reproduce problem on `master`, and it's now fixed
* Safari: ❌ Can't get it to work; giving up for now
