d5ce6dcb1d [FEATURE][processing] native drape features to z/m algorithms

2692de6ed0 [FEATURE][processing] Choice of units for non degree/unknown distances 
When an algorithm has a distance parameter in meters/feet/etc (i.e.
non-geographic distances), show a combo box allowing choice of
unit type.

(We don't (and should never) expose this for distances in degrees --
it's up to users in this situation to choose a suitable local
projection and reproject their data to match. Refs: a recent
talk by @volaya)

76c84f14d7 [FEATURE][processing] "Create parallel lines" algorithm 
This algorithm creates copies of line features in a layer, by
creating multiple parallel versions of each feature. Each copy is offset
by a preset distance.

abe4532a2c [feature][processing] "Array of Offset Features" algorithm 
This algorithm creates copies of features in a layer, by
creating multiple offset versions of the feature. Each copy is displaced
by a preset amount in the x/y/z/m axis.

97e0db6245 [FEATURE][processing] Filter Vertices by M and Filter Vertices by Z algorithms 
Adds two new algorithms, for filtering line/polygon vertices by their
M or Z values. A minimum and maximum M/Z value can be entered, and
if the vertices fall outside these ranges they will be discarded
from the output geometry.

Both min and max filter value can also be data defined, so can
vary per feature.

34b9d39b27 [FEATURE][processing] K Means clustering algorithm 
Adds a native k-means clustering algorithm.

Based on a port of PostGIS' ST_ClusterKMeans function, this
new algorithm adds a new cluster ID field to a set of input
features identify the feature's cluster based on the k-means
clustering approach. If non-point geometries are used as input,
the clustering is based off the centroid of the input geometries.
