Please add a test case for this and the next patch. It may be right, but 
it's hard to tell without a test. See dlls/kernel32/tests/console.c for 
similar tests.

Thanks,

This originates from the old wineconsole code, but I wonder if we should 
store separated font info for each screen buffer. It seems that we could 
just store it once, in console struct, instead.

Thanks,
