Subject: RrFontHeight is meaningless with pango, it will be different for every string drawn... 
X-Git-Url: https://git.brokenzipper.com/gitweb?a=commitdiff_plain;h=0417d1226c7a523cd4420195d86dd744f514b2fe;p=chaz%2Fopenbox

RrFontHeight is meaningless with pango, it will be different for every string drawn, so ask pango for the height after we tell it the text to draw. Should make text be centered vertically better when mixing fonts. Still moves a pixel down for some strings for me, but it was several before. If anyone knows more about this please mail or bugzilla etc. Also fix an indenting error.
