ImFontBaked pointers are valid for the entire frame but shall never be kept between frames.

References are only valid until a new value is added to the storage. Calling a Set***() function or a Get***Ref() function invalidates the pointer.

use unused_frames==0 to discard everything.

Was tempted to lazily init FontSrc but wouldn't save much + makes it more complicated to detect invalid data at AddFont()

Skip to the "###" marker if any. We don't skip past to match the behavior of GetID() FIXME-OPT: This is not designed to be optimal. Use with care.

When atlas->RendererHasTextures = true, this is only called if no font were loaded.

On font removal we need to remove references (otherwise we could queue removal?) We allow old_font == new_font which forces updating all values (e.g.
