# There was an error that someone found in Godot 4.4.1, but ended up being a
|
|
# different error in Godot 4.5. The fix was to hold a reference to the font
|
|
# so that TextEdit control did not lose the font when switching. This is
|
|
# the solution I came up with. Just hold a reference to all fonts we use,
|
|
# but only when we use them. Basically a lazy loader with some semantics for
|
|
# font names and location.
|
|
#

# https://github.com/bitwes/Gut/issues/749
|
|
#
|
|
# An instance of this could be used to allow users to specify their own fonts.
|
|
# It's not perect for that yet, but it is feasible.
