Subject: Make labels an even height
X-Git-Tag: pulseview-0.1.0~8
X-Git-Url: https://sigrok.org/gitweb/?p=pulseview.git;a=commitdiff_plain;h=b47d951efad3b51674e5af2fcfc29526cad6697f

Make labels an even height

This prevents some of the blurring effects to the label outline
that can be seen when the outline falls over a half-pixel.
