• clamped mat_nr (could go out of range before)
• fixed clamp angle segmentation fault

• check for offset == 0 for extrude mode
• there is a segmentation fault that occurs sometimes when using extrude, even thickness, angle clamp. It seems to appear at no specific point, just after using it a while (like for animation)

• cleaned up code a little
• fixed isolated verts in result for only rim

• removed clamps for cosf in confusion why I ever added them (cosf is defined for all finite values of float)

• fixed assertion error (had an outdated condition)
• fixed size of vert_adj_edges (was numEdges instead of numVerts) and fix for isolated verts

fixed all sort of linear algebra mistakes and cleaned up the angle calculation.

improved naming further, used a few more makros, fixed constraints calculation for offset != 0. Need to fix even and simple method for offset != 0 as well but had no time for that yet. The error in solidify_crash.blend is still unresolved.

made naming more understandable, applied all the other suggestions from above.

Ok I have fixed all the bugs I found and added a lot of code to support duplicates. Also I added the offset property that was missing. I have a file with my test objects that I will add to this comment.

fixed a bug where very complicated geometry would create wrong loops resulting in all sorts of failure

fixed normalized vertex normals for curves

changed the obsolete designated initializers to standard syntax

As I understand the apply operators, they should all leave the visuals exactly as is, so this is a bug. It completly not doing anything with axis angle representation is a bug for sure though, but even the problem with the quaternion isn't, that it rotates the cube, the problem is, that the resulting delta quaternion is not a unit quaternion (which all rotation quaternions are unit quaternions)
