Subject: Remove undocumented -linebias argument
X-Git-Tag: v1.11.90~28^2~2
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=30eed8c08088b733e4565a590c371083e8180205;p=tigervnc.git

Remove undocumented -linebias argument

This is a development flag with no real use, so remove it to clean up
the code.
