Image snapshot test is very unreliable

Image snapshot test is very unreliable: ~15% difference and it's making CI fail.

• As a temporary fix, just increase the tolerance on the test to make CI work again
• Fix the root cause (perhaps antialias=false would fix it)

Turns out changing the comparisonMethod to ssim made it work

Still seems to be a bit inconsistent, see https://github.com/MarcellPerger1/minecraft_clone_1/actions/runs/9618002711/job/26530972442

The problem isn't with my tests (probably), it's with my code or with WebGL. It puts the texture coords a bit off (and sometimes more than just a bit off) so the tests fail as the textures are off.

It seems to have weeks where it works well and weeks where it just doesn't want to work at all.

Finally found the reason: the fix for the weird lines between blocks (#86) doesn't work properly

• It recalculates the mesh only every n frame/seconds so isn't consistent between desktop and the SLOW 🐌 GH actions
• and/or it doesn't work for the massive (other-way?) inaccuracies of the GH action runner's non-HW accelerated 'WebGL'.

This means that it over-compensates and creates this:

Therefore, I'll reopen #86 and hope that the fix for that one fixes this one too.
