Adaptive stroke causes flood fill artifacts #94

Closed jakubfiala closed 8 months ago

AS seems to be the cause of these. The fill works perfectly if only smoothing is enabled.

turns out this is happening because of antialiasing, which creates semi-transparent pixels around the stroke. I've addressed this to an extent in b1986fd but there are still cases where the issue persists (e.g. draw a closed stroke, fill it with a different colour, then fill that same area with another colour).

from my testing I deem the current state good enough
