Elias Naur 258033d0b0 gpu: eliminate gaps by ensuring consistent transformations
This is another attempt at fixing the issue described in [0], the
previous attempt was reverted[1].

This change fixes the issue by tracking resolved transformations and
ensure that all segments within a path share a single transformation.
