Description

fixed rectilinear interlaced interface pattern not always applied
fixed rectilinear interlaced interface random layers not always rotated
support interface layers rotation angle always 0°/90° as opposed to -45°/+45°
- -45°/+45° is reserved for snug supports
decoupled raft layers (base + interface) orientation from support orientation
unified raft support orientation
- always at 0° except first raft layer that is at 90°; it was like that for tree support, if it was good enough for those, than why not for every type of support
make raft interface layers always interlaced
raft interface layers rotation angle always 0°/90° as opposed to -45��/+45°
- this way it is never aligned to the object bottom layer
make first raft interface orientation always perpendicular to the support base layer beneath it
- if raft has only one base layer (it is at 90°) than the interface above it is at 0°

There are other fixes too that became an issue only on the path to fixing the above mentioned ones.
