No, actually in both cases the precedence is "force" so all spaces
survive the resolution process.
So, just to check I understood:
- according to the pdf specifications between two words there is
1 word space + 2 letter spaces
- according to the xsl recommendation there is
1 word space + 1 letter space (or better, two half letter spaces)
- fop currently puts just a word space
Is this correct?
But I still don't understand what the words concerning "adjusted values
between word spacing and letter spacing" are supposed to mean ...
However, while I was out for a few hours I was thinking about this and I
came to the conclusion that it may make sense to keep an array of
character offsets as an attribute of a WordArea in the area tree.
It would probably be the best way to deal with kerning too.
My only concern is about the resulting pdf size: if we specify an offset
for each character, wouldn't it become (at least) twice as big as before?
