renderer: Use interface to render offset
2021-01-06 09:46:57 -05:00
#pragma once
Move most action state out of renderer The renderer now only stores the positions of the actions because that is specific to the renderer and because the actual position can only be finalized after all the rendering is done because intitially the positions are relative to the alignment and not the bar.

Move trivial formatting state into tags::context The variables storing the current colors, attribute activations and font were only used in a single place and can easily also be read from the context. This allows us to remove a lot of the state of the renderer.
