Thanks Adrian. I must have misunderstood you previously regarding layerspace
vs imagespace.

Given that this is also what I have implemented and feels is the the right
thing I strongly favour committing my patch. If we were to require
paintdevice to take imagespace coords we would break encapsulation and
compartmentalisation rules. In this respect my patch is more clean. Wishing
for a facade is a good thing but this should be to hide the tile structure,
not to swallow things outside the paintdevice.

just my two cents worth.

Boudewijn, could you please make a decision, as I'm not getting anywhere
waiting. I would really like to finish this layer thing this weekend, and I
have the time and will, but unless you decide I'm stuck.

best regards
