I somewhat dont like this answer :)
I thought that vf modules could selectively buffer strides or not.
Ie pass trough all strides that do not contain any drawn text and buffer
only those which are overwritten. Isnt that possible ? Or do i mix it up
with vp ?

Do you have any other ideas how this could be done in a more or less
fast way ?

I wont plan neither for g2 nor for g3 unless there is at least a core
available. Thus i want to see this fixed in g1.
