hz MkIV

hz MkIV

[Steffen Wolfrum]

Hi,

in MkIV hz is bound to the found (thus the speed increase).

Now, how do I assign different degrees of hz to different areas?
Say, moderate hz in the normal text and more drastic in controlled  
situation, like this:

% main text:
\setupbodyfont[postscript,10pt]
\setupalign[block,hanging,hz]

% and in controlled situation:
\setupwhatever[align=hzXXL,style=...]


This doesn't work:

fonts.expansions.classes['NormalQuality'] = {
     stretch = 1, shrink = 1, step = .5, vector = 'default', factor = 1
}

fonts.expansions.classes['DrasticQuality'] = {
     stretch = 2, shrink = 2, step = .5, vector = 'default', factor = 1
}


\definefontfeature[hz][default] 
[protrusion=pure,expansion=sstquality,mode=node,script=latn]
\definefontfeature[hzXXL][default] 
[protrusion=pure,expansion=sstquality,mode=node,script=latn]

\usetypescript[postscript]
\definetypeface[postscript][rm][serif][times][default][features=hz]%  
<- what to do with hzXXL ???

just define an extra typeface with different characteristics

(i can imagine that at some point we can have an extra multiplication 
factor, like (lowlevel) \effactor or so but that demands a patch of luatex)

Well, how to define an extra typeface to a hidden predefined  
typescript "postscript"?
The following might work, but it is admittedly a very, very ugly hack  
(redefining poor sans helvetica  ...).

Thus, please: any improvement very welcome!!

Thanks,
Steffen
