8398aae04b [needs-docs][processing] Use input layer data type for gdal algorithms 
when appropriate:
- warp (i.e. reproject)
- translate (i.e. file format conversion)
- rearrange bands
- clip by extent/mask

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.

c6a91dab09 [FEATURE] Use native interpolate point method instead of GEOS method 
Because:
- Exactly follows curves and doesn't require segmentizing input geometry
- Also interpolates z/m values if they are present in input geometry
- Is faster

8365335fd3 [FEATURE][processing] Interpolate point on line algorithm

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.

63fd4bab2a [processing][FEATURE] Store models inside QGIS project files 
Allows processing models to be stored inside QGIS project files,
so that opening the project makes that model available.

Some models are so intrinsically linked to the logic inside
a particular project that they have no meaning (or are totally
broken) outside of that project (e.g. models which rely
on the presence of particular map layers, relations, etc)

This change allows these models to be stored inside that project,
avoid cluttering up the "global" model provider with models
which make no sense, and making it easier to distribute a single
project with these models included.

Models are stored inside projects by clicking the new "embed
in project" button in the modeler dialog toolbar. Models can be
removed from a project from the model's right click menu in the
toolbox.

526e590c8d [FEATURE][processing] Add "raster pixels to points" algorithm

create a new "pixels to points" algorithm, which creates a point
feature at the center of every pixel. nodata pixels are skipped.

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)
