72161 - Back-end to extend the support of stretchy chars

Status: RESOLVED FIXED

(Core :: MathML, defect)

Description

[rbs]

I will be attaching a patch that extends the handling of stretchy chars in
accordance with the system that I described at the above URL. The patch allows
the stretchy code to support mixed glyphs from different font families when
these are specified with the 'code@font' notation in the MathFont Property File.
The patch also allows using common code points in the Unicode' Pivate Use Area
for glyphs of same rank but in different font famlies (this way, assignments to
the PUA are kept minimum).

To summarize, with this patch, the stretchy code now supports the system that I
described in its entirety.

Converting the mapping tables and property files to the new Unicode points 
published in MathML2 is the remaining piece of the puzzle (bug 71408). The patch
only includes the conversion of the Symbol font.

Want to give me r/sr on this guys?

Also completed (in my tree) the migration of the entities & operator 
dictionary to the new MathML 2.0 unicode points (bug 30543), and completed
the migration of the MathFont Property Files of Adobe' Symbol font and TeX
fonts (CMR10, CMMI10, CMSY10, CMEX10) to agree with these code points and
the stretching process. So the PUA stub has expanded quite a lot.

Checked-in. I will land the stretchy data later when they are ready (it is
rather tedious to prepare so many of them in one go.)
