FIXED issue #128: Question about rendering unicode in plot labels: Unicode characters were not rendered if they are not in the currently active font, as fallback-rendering was switched off. It is now switched on again for text and verbatim nodes. Thanks to user:fpalazzolo for reporting this bug

FIXED font rendering was not always anti-aliased
