0d200623b1 [FEATURE][processing] Add non-joinable output to Join by Location alg 
Allows unjoinable features to be saved to a separate optional layer

773371a143 [FEATURE][processing] Join by field value can export unmatched records, 
and reports counts of matched/unmatched features

This gives an explicit warning to users when features were not matched,
and optionally allows them to save non-matching features to a layer.

8365335fd3 [FEATURE][processing] Interpolate point on line algorithm 
This algorithm creates a point geometry interpolated at a
set distance along line (or polygon boundary) geometries.

7ef5631d6b [FEATURE][processing] Line substring algorithm 
This algorithm returns the portion of a line (or curve) which falls
between the specified start and end distances (measured from the
beginning of the line).

Z and M values are linearly interpolated from existing values.

526e590c8d [FEATURE][processing] Add "raster pixels to points" algorithm 
Refactor the existing "raster pixels to polygons" algorithm and
create a new "pixels to points" algorithm, which creates a point
feature at the center of every pixel. nodata pixels are skipped.

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.

5b7eefa6ae [FEATURE][processing] New 'Raster pixels to polygons' algorithm

corresponding to each pixel from the raster and a single field
containing the band value from the raster.
