this changes adds nofill areas to Activ, GatPoly, M1-5 and TM1-2. These areas are not super nicely drawn but at least the area around Passiv in the sealring is now marked as nofill.

Additionally, sealring includes not a prBoundary.drawing rect around the entire chip.

Add data types to generateCorner and combineLayerAndDelete to use
these functions also for data types except 'drawing'.

@KrzysztofHerman can you please verify this is correct? I had to add those areas manually for ElemRV.

Draw a prBoundary.drawing rect around the chip which is required
for tape-out tools.

Additionally, draw nofill areas around the sealring Passiv area
since this shouldn't contain any filled material. Adds nofill
areas for Activ, GatPoly, M1-5, TM1-2.

This is how the sealring looks like.

Hi @dnltz, I have verified how the fillers are generated in the PVS and what it does it detects the EdgeSeal.drawing inner area and shrinks it to meet DRC. Then this layer is used as extent_all_layers equivalent in the current solution. From this point of view this functionality of nofill areas will not be necessary,

@KrzysztofHerman okay, another topic I should address when filling the chip. I assume I can close this issue?

For now I do not see anything specific to add. Let's close.
