Bug#370750: libpango1.0-0: Many fonts are selected incorrectly

[Dylan Thurston]

Package: libpango1.0-0
Version: 1.12.3-1
Severity: normal

On my system (with cm-super installed), if I go to a GTK font
selection dialog and select Family 'Computer Modern' and style
'Typewriter', I get the font Dunhill.  (Exactly which font you get is
slightly random, but it will generally not be correct.)

If I understand correctly, this happens with any font that has more
styles than the standard normal/bold/italic/bold italic.

The reason is that in pangofc-fontmap.c, the function
pango_fc_font_description_from_pattern ignores the FC_STYLE element of
the FcPattern it is passed.  (It only looks at the weight and slant of
the font.)  For the Computer Modern family (and several others), this
element contains crucial information that cannot be ignored,
especially that FC_STYLE is what the user is directly picking in the
GUI.

(Bug #354537 is probably the same as this bug, but I haven't
investigated the OpenOffice issue mentioned there so I'm not
reassigning that bug.)

Peace,
	Dylan Thurston
