fix really overscaled lines

[ansis]

fix #16018

We resample lines after sharp corners in some situations. When tiles were really overscaled, sometimes we didn't have enough precision to represent the resampled vertex because it was too close. Disabling this after a certain point prevents this.

It looks like some kind of tests for vertex buffer size are failing. Where are these set and how can they be updated?
