Hi,

A few things

(1) Thomas and I picked up the facing floats thread. I will probably 
remove the experimental code from mkiv and only work on the lmtx 
implementation. The same can be true for streams.

(2) The \limits and \nolimist etc commands are actually modifiers and so 
are \Umathadapttoright and \Umathadapttoleft. Because we have a couple 
of 'handy' options in several math constructs in the engine I decided to 
add a few more modifiers to (ab)use those features too. The next 
examples are for 'math detail lovers':

% \displaylimits
% \limits
% \nolimits
% \ordlimits (maybe replace that one now or maybe no longer needed anyway)

% \Umathadapttoleft
% \Umathadapttoright
% \Umathaxis
% \Umathnoaxis
% \Umathphantom
% \Umathvoid
% \Umathopenupheight <dimension>
% \Umathopenupdepth  <dimension>
% \Umathlimits
% \Umathnolimits

I'm still wondering about some interfacing but that depends on it being 
used (at all) but at least we can finetune a bit more abstract if we 
want to. It is also fun to play with (come up with new math notations 
and so).
