Added transparency to areas with no vector data.
...
Originally the background colour defaulted to white with no transparency for areas without vector data. I have added an alpha channel to the geotiff and set it zero (full transparency) for areas with no vector data. This could be optional, in case the user wants a solid background.

Remove context-unaware QgsCoordinateTransform constructors from Python bindings
...
This forces Python code and plugins to become datum transform
aware, and given that upgrading python code is easy (just
add QgsProject.instance() as a new argument to the constructor)
it's relatively painless to force this on PyQGIS users.
Also fix upgrade the easy QgsCoordinateTransform c++ constructors
where the project is available, or where using QgsProject::instance()
is safe to do.
For others, just avoid the deprecated warnings until we can
get access to the correct project instance where the transform
is being constructed.

Refactor fields configuration in the modeler does not insist on layer

Inside the modeler, there is not enough knowledge about the layer on

Let's be graceful with error messages here therefore.

Fix geometry snapper sometimes creates unwanted overlapping segments
...
when snapping line layers
Because the default behavior of the snapper is to insert extra
vertices into the snapped geometry in order to make it 'follow'
the reference geometries exactly, this can result in unwanted
results for line layers where the resultant snapped layer
has overlapping line segments.
Since we can't always know what the desired result is that the
user wants (maybe they do want overlapping lines), instead
give them control over the result by exposing extra enum
options which never insert extra vertices.
