new experimental

new experimental

[Hans Hagen]

Hi,

the experimental branch of the garden distribution has a prelude to the 
new math font subsystem

- less definitions, so faster (but some things might not yet work)

- unicode math (but mojca, aditya, taco and i are in the process of 
checking and completing the definitions)

- faster startup time of mkiv as well as less memory usage

- using runtime virtual fonts which permits more math alphabets (as un 
unicode) but not all are defined now (not all make sense)

since this is evolving, if you use experimental, you need to update on a 
regular basis (mkiv as well as the luatex bin) but mojca keeps things 
nicely in sync so that should be done automatically for lin/win/osx

After upgrading, \chem{CO_2} still gives me:

! Font \*palatino10ptmmmrrm* has only 7 fontdimen parameters.

sure, you need to wait till mojca has synced both context and luatex

Hi, Hans,
please test the following formulas. All of them come from my thesis,
and MKII typeset them right. MKIV produce the wrong result.
I am using the nightly build from w32tex since the luatex binary in
the minimals repository cannot generate the format correctly.

Re: new experimental

[Yue Wang]

Hi, Hans:

Now the results are ok.
However, luatex's result seems a little bit smaller than pdftex's
result (Pixel level comparison)?

http://yuleopen.googlepages.com/xetex.pdf
http://yuleopen.googlepages.com/luatex.pdf
http://yuleopen.googlepages.com/pdftex.pdf
