5710709c72 Add extra hash to processing hillshade test 
At this stage the raster processing tests just test that the
algorithm executes, and generates an output file - there's
no way to validate that the provided hashes are valid
outputs or not

05484dceb6 [FEATURE][processing] Rotate features algorithm 
Allows rotation of features by a set angle.

The rotation can occur around a preset point or the individual
feature's centroids.

4232b93539 [FEATURE][processing] Add "segmentize" algorithms 
Adds two new algorithms which expose QgsGeometry's methods
for segmentizing curved geometries.

"Segmentize by maximum distance":
The segmentization is performed by specifying the maximum
allowed offset distance between the original curve and the
segmentized representation.

"Segmentize by maximum angle":
The segmentization is performed by specifying the maximum
allowed radius angle between vertices on the straightened
geometry (e.g the angle of the arc created from the
original arc center to consective output vertices on the
linearized geometry).

e12621ce2a Add API method to remove duplicate nodes from geometries 
Removes duplicate nodes from the geometry, wherever removing the
nodes does not result in a degenerate geometry.

By default, z values are not considered when detecting duplicate
nodes. E.g. two nodes with the same x and y coordinate but
different z values will still be considered duplicate and one
will be removed. If useZValues is true, then the z values are
also tested and nodes with the same x and y but different z
will be maintained.

Note that duplicate nodes are not tested between different
parts of a multipart geometry. E.g. a multipoint geometry
with overlapping points will not be changed by this method.

The function will return true if nodes were removed, or false
if no duplicate nodes were found.

Includes unit tests and a processing algorithm which exposes
this functionality.
