Subject: (MWDevice): New member resy.
X-Git-Tag: REL-1-3-0~237
X-Git-Url: http://git.chise.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f7db2840753db7b4316761f2287c1e7b42b5d508;p=m17n%2Fm17n-lib.git

(MWDevice): New member resy.
(xfont_open): Set ascent, descent, and max_advance members of
rfont.
(xft_open): Likewise.
(device_open): Compare also screen_num to find a device.  Set
device->resy and frame->dpi.
