Workaround new text renderer (#467)

* add time markers

* workaround wip

* rename to render_data

* content into layout

* breakline as spanelement

* line number

* part one: compute shape by line

* update

* todo: fix clusters

* correct last line

* wip correction on clusters

* correction

* clustering support

* avoid compute total x since break_without_advance_or_alignment doesn't care

* correct line height calculation

* update lint
