Comment 3 for bug 1022076

Took a look at this.

The patch has no effect here. Reason is, drilling holes are usually vias with the "hole" flag, but the patch acts on Pins, only. Also, vias are usually fully covered with solder resist, no hole in the mask at all. As no sample was provided I'll have to make a hand-edited one.

I think this whould be a reasonable solution:

- Handle vias and pins the same regarding solder mask.

- Increase mask hole only if it was > zero before. Currently vias are handled this way.

- Take for both the bigger of thickness and drill hole as reference for gap calculation.
