Of course no one really needs this because OpenType Lucida fonts have replaced the
Type1 versions.
The next goodie table is dedicated to the de facto standard T E X font Latin Modern.
There is a bit of history behind this file. When we started writing ConT E Xt there were
not that many fonts available and so we ended up with a font system that was rather
well suited for the predecessor of Latin Modern, called Computer Modern. And because
these fonts came in design sizes the font system was made such that it could cope efficiently
with many files in a font set. Although there is no additional overhead compared
to small font sets, apart from more files, there is some burden in defining them. And,
as they are the default fonts, these definitions slow down the initialization of ConT E Xt
(which is due to the fact that the large typescript definitions were loaded and parsed).
So, at some point the decision was made to kick out these definitions and move the burden
of figuring out the right size to Lua. When Latin Modern is chosen as font the effect
is the same when design sizes are enabled. But, instead of many definitions (one for
each combination of size and style) we now have an option. A non-designsize typeface
is defined as follows:
\starttypescript [modern,modern-base]
\definetypeface [\typescriptone] [rm] [serif] [modern] [default]
\definetypeface [\typescriptone] [ss] [sans] [modern] [default]
\definetypeface [\typescriptone] [tt] [mono] [modern] [default]
\definetypeface [\typescriptone] [mm] [math] [modern] [default]
\quittypescriptscanning
\stoptypescript
The designsize variant looks like this:
