2D SDF artifacts #123

Closed virtualritz closed 5 months ago

The SDF preview looked smooth before but now I get tile-like artifacts and curvy stuff looking jagged:

I dunno when this (visual) regression got introduced since I didn't play with fidget for a month or more though.

This is intentional (#102), to make rendering cheaper. The boundary is still pixel-perfect, but regions that have been proved empty / full are drawn using interpolation from the corners, instead of checking every single pixel. SdfPixelRenderModel still implements the previous behavior.

Would you accept a PR that adds the old mode as 2D SDF (Precise) to the Config menu?

Sure, that would be fine!
