This commit adds the mathed command \mathds that selects a
font more appropriate than \mathbb for typesetting the
mathematical symbols for the natural (N), whole numbers (Z),
rational numbers (Q), real numbers (R), complex numbers (C),
and some others.
As in the \mathbb case, only capital letters are supported,
but in addition one can also typeset a symbol often used for
representing the indicator function (\mathds{1}) and the
letters a, h, k.
Fixes bug #11887.
While math style (scriptstyle,...) is not really something that can be
set, it is useful for text subscripts and superscripts and therefore
it makes sense to handle it in some places.
With this change, style is still not a first class feature, but good
enough for now. In particular, it is taken into account in update().
Move math style to FontInfo and compute the font sizes for scriptstyle and
scriptscriptstyle according to standard proportions: 0.73 and 0.55.
This is simpler and more accurate. It also fixes the font size of
${\scriptscriptstyle {\textstyle A}}A$ which exposed the limitations of the
previous approach.
The stmaryrd package adds support for lots of math symbols, using a font
designed to accompany the computer modern fonts. The changes in detail:
- Fix generate_symbols_list.py to work with stmaryrd.sty. It loooks like it
was automatically translated from a perl version and never used.
- Generate the new symbols in lib/symbols using generate_symbols_list.py and
add some manual adjustments
- Generate stmary10.ttf by a simple ttf export from stmary10.sfd with fontforge
- Add license info for stmary10.ttf
- Create a test file with all symbols from stmaryrd.sty. Actually it would be
nice to have this for the other fonts as well.
- The mechanics: lyx2lyx, tex2lyx, font machinery etc.
* Font::FontBits -> FontInfo
* Font::FONT_XXX -> all enums transfered to FontEnums.h and renamed to FontXxx
I've replaced Font uses with FontInfo were the language() member was not needed, basically all draw() and metrics methods. There's one problematic cases with InsetQuotes which I solved by taking the Buffer main language.
