340cf93f93 [FEATURE] New algorithms to add Z/M values to existing geometries 
Allows upgrading geometries to include these dimensions, or
overwriting any existing Z/M values with a new value.

Intended mostly as a test run for QgsProcessingFeatureBasedAlgorithm

1a41624370 Add QgsProcessingFeatureBasedAlgorithm subclass 
An abstract QgsProcessingAlgorithm base class for processing algorithms
which operate "feature-by-feature".

Feature based algorithms are algorithms which operate on individual
features in isolation. These are algorithms where one feature is
output for each input feature, and the output feature result
for each input feature is not dependent on any other features
present in the source.

For instance, algorithms like "centroids" and "buffers" are feature
based algorithms since the centroid or buffer of a feature is
calculated for each feature in isolation. An algorithm like "dissolve"
is NOT suitable for a feature based algorithm as the dissolved output
depends on multiple input features and these features cannot be
processed in isolation.

Using QgsProcessingFeatureBasedAlgorithm as the base class for feature
based algorithms allows shortcutting much of the common algorithm code
for handling iterating over sources and pushing features to output sinks.
It also allows the algorithm execution to be optimised in future
(for instance allowing automatic multi-thread processing of the
algorithm, or use of the algorithm in "chains", avoiding the need
for temporary outputs in multi-step models).

71b9ce25c6 On first run, try to guess a good default icon size based on screen DPI 
Otherwise icons are miniscule when loading QGIS on hidpi screens, and
users must know that they need to manually change the icon size
to make it usable...

dbd50b4bdd On first load, default to 80% of current screen size for main window 
Using a fixed default window geometry wasn't working well anymore -
it made the default window size tiny on hidpi screens.

2b2d5e3637 [FEATURE] Give access to geometry errors 
When methods are called that use GEOS to create new geometries, the
result geometries now contain information about what has gone wrong in
case of an error.

In practice, this means it's possible to give more detailed information
in place (and not only in the message log) when things like processing
algorithms fail.
