* Font handling (interface).
|

|
|
* These functions provide font related services. They all work on UTF-8 strings
|
|
* with lengths given.
|
|
*
|
|
* Note that an interface to painting is not defined here. Painting is
|
|
* redirected through platform-dependent plotters anyway, so there is no gain in
|
|
* abstracting it here.
