Was always returning a point not on the surface! (0,0). Use the
GEOS method instead.

...smallest diff for a new feature ever ;)

Also properly closes the iterator when a fallback orderby is used

This allows defining the order in which features are processed by
renderers.

And some sip fixes

…ipponen

The settings were allocated in the stack
causing a segfault when accessed from the slot

Fixes qgis#14021

A number of elements have both a <Name> and a <Title>. The Name is a text string used for machine-to-machine
communication while the Title is for the benefit of humans. For example, a dataset might have the descriptive Title
“Maximum Atmospheric Temperature” and be requested using the abbreviated Name “ATMAX”.

User can already set title for layers, groups and project. OWS name is based on the name used in layer tree. This name is more a label for humans than a name for machine-to-machine communication.

To add the capability to users to define Name as a text string for machine-to-machine communication, this pull-request adds:
* short name line edits to layers properties
* WMS data dialog to layer tree group (short name, title, abstract)
* short name line edits to project properties
* add a regexp validator "^[A-Za-z][A-Za-z0-9\._-]*" to short name line edit accessible through a static method
* add a TreeName element in the fullProjectSettings

If a short name has been set for layers, groups and project it is used by QGIS Sever as the layer name.

Fix qgis#14016

This reverts commit c1b512f.

It has to be done this way. Just adding updateSelectFeature() in a few places
is not enough, because then the rubber band will still not be updated after
an undo operation.

QGIS crashes when using the Globe plugin if this package is not installed,
as reported in QGIS issue qgis#9818 [0] and Debian Bug #808817 [1].

To finalize commit 3472ac8 update processing to well manage default value

- Broke into per class testcase
- Each method tries to test only one aspect of behavior
- Use unittest assertions for better error output
- Removed non-existant serialize functionality from tests
- Test BooleanParameter

Conflicts:

* Fix a crash with WhenThenList
* Check implicit sharing with all test expressions.

The ERROR macro is already defined by WinGDI.h and so the warning C4005 'macro redefinition' was thrown.
The constant 0xFE is out of range for (signed) 'char' and so the warning C4309 'truncation of constant value' was thrown.

This avoids corrupted project files when crashing during the preparation of the XML data to write to the project file, e.g. due to a faulty plugin.

If an error occurs while loading the project file, prompt the user to load the backup file instead, if it exists.

When embedding layers, reread the external project file if its lastModified timestamp changed.

Since it's just a int64, it's faster to pass by value

The term "Not supported" is not appended to the label when it is already present.
The term is removed when no longer applicable.

(an attempt to debug test failures in debian)

- remove use of namespace blocks (avoids unnecessary indentation)
- cleanup includes
- remove old std::cout debugging blocks
- move some documentation from cpp to headers
