9fa4e776db [FEATURE][processing] Extract nodes algorithm now saves node 
index, distance along line and angle at node

Also correctly handles null geometries

8db9284cb3 [FEATURE][processing] Optimised points along geometry algorithm 
Supports also polygon geometries, handles null geometries,
and records the original line angle along with the distance
for each point.

e9423dc4dd [processing] Rework centroid algorithm to handle non-polygon layers 
The existing polygoncentroids algorithm has been deprecated
(and hidden from the toolbox), and a new, generic centroids
algorithm added which works with lines and multipoints

71ebdb8f69 [FEATURE] Optimise processing clip algorithm 
Before the algorithm was written to optimise clipping a few
features against thousands of mask features. The revised algorithm
is optimised for clipping thousands of input features against
a few mask features.

Given that this second operation is much more likely, it makes
sense to optimise for this use case.

I've also applied some other optimisations like taking advantage
of spatial indexes on the providers, using prepared geometries
and also only applying an intersection operation if the geometry
isn't wholly contained by the mask geometry.

Benchmarks:

clipping roads layer with 1 million lines against 2 polygons

before: 5 mins 30 seconds
after: 10 seconds

clipping address layer with 5 million points against 2 polygons

before: 50 minutes
after: 30 seconds

30fcaed634 [FEATURE][processing] New algorithm for merging connected lines 
This algorithm joins all connected parts of MultiLineString
geometries into single LineString geometries.

If any parts of the input MultiLineString geometries are not
connected, the resultant geometry will be a MultiLineString
containing any lines which could be merged and any non-connected
line parts.

b7a4e20627 [processing] add Rectangles, Ovals, Diamonds algorithm (fix #11575) 
This is direct port of abandoned "Rectangles, Ovals and diamonds" plugin.
There are two algorithms: one uses fixed values and second — variable
values from attribute table. Test for fixed distance version included.
