Fix titles when container titles contain UTF-8 characters

The title and marks textures would have their height set from the
config's computed max font height, but the textures were not regenerated
when the config's max font height changed which made a gap appear.
Rather than making it regenerate the title textures every time the
config font height was changed, I've changed it to just make the
textures the height of the title itself and fill any gap when rendering.

Also, the title_width and marks_width variables have been renamed to
make it more obvious that they are in output-buffer-local coordinates.

Fixes #1936.
