add option for equal distribution on surface features

[avxmw]

These are to identical cylinders (h=60mm, d=30mm) which are covered in a surface on z axis with surface being "Noppen", form "Halbkugel" and depth of 3mm. On the left distance is set to 5mm, on the right to 3mm.

As can be seen on the left cylinder, there are empty spaces likely resulting from the circumference not being perfect for the distance configured. For reasons unknown to me these are not in a pattern I understand, neither vertical, nor diagonal it seems.

Would be nice to have options for:

1. give number of features and equally space them
2. alignment: vertical/horitontal, diagonal/hex (maybe others)

Likely not directly related, but when zooming in onto the left one there are artifacts in some of the cavities

@avxmw Thanks for the clear pictures! The gaps are a bug, not the circumference: around a cylinder the spacing is already rounded so a whole number of bumps goes round (at 5 mm you get 19 at 4.955 mm, at 3 mm 31 at 3.04 mm). Some bumps are wrongly treated as if they sat on a sharp edge and are left out entirely, and the broken cavities in your close-up very likely come from the same thing. Until that's fixed, switching off Keep sharp edges smooth in the texture settings brings nearly all of them back.

On the arrangement: bumps are always staggered (hex) at the moment, straight rows aren't available yet.

@avxmw the fix is out now in layerling 1.124.0. On your cylinders every bump is in place now, with Keep sharp edges smooth on as well, and the torn cavities are gone. There is also a new setting Arrangement for bumps: staggered as before, or straight rows and columns. The guide has the details.
