The commit d44f1eba2fed18b3fef8d8865d79b3b6d8bc4d69 seems to break some WMS 1.3.0 client and WMS compliancy.
The commit d44f1eba2fed18b3fef8d8865d79b3b6d8bc4d69 has been written to fix an issue with QGIS WMS Client and to render image like other WMS Server.
This commit has been written to fix issue introduce by d44f1eba2fed18b3fef8d8865d79b3b6d8bc4d69.
It is based on MapServer code:
* https://github.com/mapserver/mapserver/blob/master/mapdraw.c#L115
* https://github.com/mapserver/mapserver/blob/master/HISTORY.TXT#L3768
And take account of axis invertion for output CRS.

- Checking/unchecking a group doesn't change the check state of its children.
A node is visible if and only if it is checked and all its parents too.
- There is no more a semi-checked state for a group
- Ctrl-clic on a unchecked group will check the group and all its descendants.
- Ctrl-clic on a unchecked layer will check the lager and all its parents.
- Ctrl-clic on a checked group will uncheck the group and all its descendants.
- Ctrl-clic on a checked layer will uncheck the layer and all its parents.
- Those actions are available in contextual menu items in the tree view.
- Invisible layers because they or their parent(s) is unchecked are greyed out.
- Remove some non-base class empty destructors. These add no value
and it's better to let the compiler auto generate optimised versions
- use virtual ~Class = default instead of virtual ~Class {}
Adds a new method to QgsVectorDataProvider to truncate the layer.
The base implementation requires DeleteFeatures capability and
is not optimised. Providers can return the FastTruncate capability
and override the base implementation with a provider specific
optimised version. This is done in this commit for the Postgres
and Spatialite providers.
Previously this method would only succeed for providers which
explicitly implement it. Now, providers which do not implement
changeFeatures but do support both ChangeAttributeValues
and ChangeGeometries capabilities will use a non-optimised
version of changeFeatures which calls changeAttributeValues
and changeGeometries in turn.
This makes QgsVectorDataProvider::changeFeatures easier to use
in scripts - instead of writing manual fallbacks for providers
which do not implement it you can instead safely call this
method regardless of the provider and it will succeed wherever
both the attributes/geometries can be changed.
Also add a provider unit test covering this.
This is replaced with a QVariantMap. It was never really more than this in the
past and with the switch to QgsConfigurationProperties, there is really no
longer any reason to assume that this will change.
This class holds a QVariantMap to manage key-value-pairs where each
value can be a string, bool, int, double or itself a map and can be
stored to and restored from XML.
This commit implements the improvements described at:
https://lists.osgeo.org/pipermail/qgis-developer/2016-September/044393.html
The QgsRasterMinMaxWidget now offers a seetting to specify that the statistics
should be computed each time the canvas extent changes.
Other changes:
- the content of the QgsRasterMinMaxWidget is now persistant.
- there is no longer any Load button. The global Apply / OK button of the raster
properties dialog has this effect.
- the default "limits" for single band raster is now MinMax and not CumulativeCut
- the default "limits" can be configured for single band, multi band single byte and
multi band multi byte
- "Strech using current extent" honours the "limits" instead of forcing min/max.
