\startsubject[title=A Summary]
\startitemize
\startitem
{\bf the macro package's view:} just a font like any other but it needs to configure
some extra color related properties
\stopitem
\startitem
{\bf the engine's view:} depending on the technology a normal font that needs a bit
special treatment or needs to be dealt with as collection of graphics
\stopitem
\startitem
{\bf the viewer's view:} regular outline glyphs or images tagged as kind of
characters so that their unicode representation can be cut and paste
\stopitem
\startitem
{\bf the user's view:} more pictures than glyphs although some people one can
communicate using them
\stopitem
\stopitemize
So, in practice, for most \TEX\ users it's probably not a high priority font but more a fun
one.
\stopsubject
\startsubject[title=Technologies]
As each vendor came up with something, we have to deal with a all kinds of formats. And or
course, as eagerness pushes things on the market before it's perfect we now have to deal
with all of them.
\startitemize
\startitem
{\bf overlapping glyphs:} this technique uses the \type {colr} and \type {cpal} tables
and is actually a quite clean technology, you can combine in different ways
\stopitem
\startitem
{\bf svg graphics:} this technique uses the \type {svg} table that contains a svg vector
image
\stopitem
\startitem
{\bf bitmap graphics:} this technique uses for instance \type {sbix} tables that can have
various graphic images
\stopitem
\stopitemize
The first two are already supported in the \CONTEXT\ font loader and processor
for a while, the last one was added recently.
\blank
Only the overlapping method is useable for the tens of thousands of skin tone combinations of
families, (kissing) couples, and professions.
