font-list% object maintains a list of
font%
objects to avoid repeatedly creating fonts.
A global font list, the-font-list, is created automatically.
Creates an empty font list.

automatically added to the list). The arguments are the same as for
creating a
font% instance.

Changed in version 1.4 of package draw-lib: Changed size to allow non-integer and zero values.
