Subject: [PATCH] DiskUsage: fix infinite loop when computing tab width

Stop when we have a solution that is within 1px of accurate. Since tab
width are rounded to the nearest pixel anyway, there is no need to
compute further, and this could otherwise never converge due to rounding
errors.

Fixes #15944.
