[vector file writer] use field type to save attribute values 
(relying on attribute value type isn't reliable under certain
scenarios, including memory layers created through a processing
python algorithm)

d5ce6dcb1d [FEATURE][processing] native drape features to z/m algorithms 
Sets vertex z/m values to values sampled from a raster band.

Values can optionally be scaled using a (data definable) scale value.

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 
Converts a raster layer into a vector layer, with a polygon feature
corresponding to each pixel from the raster and a single field
containing the band value from the raster.
