Previously, annotation size and position always used pixel units. This
did not work well when exporting layouts, resulting in tiny annotations
(it also caused issues when moving projects between hidpi/non hidpi
displays).
Instead, use millimeters for annotation size and position so that the
appearance is consistent across displays and works correctly in layout
exports.
Add lots of unit tests covering this.
Fixes#18373
In OGC WMS standard, the empty string represents the default style.
QGIS Server when it parses the parameters, QGIS Server when it parses parameters it removes empty parts.
When all requested styles are default ones it's equal to an empty parameter STYLE, as defined in the standard.
When only one layer is requested, there is no issue with custom or default style.
When multiple layers are requested and some with custom styles, because QGIS Server does not retain empty strings, it loses the layer / style match.
To fix it, keeps empty parts for not empty styles parameters.
In QGIS 3.4, Selection can be printed in Image output and not in PDF or SVG output.
A fix has been done 2752f83 to fix inconsistent use of layout render context flags, and draw selection is activated with a flag.
In QGIS Server 2.* the WMS GetPrint request could genrate JPEG image. QGIS Server 3.4 has lost this capabilities.
```
<ServiceExceptionReport xmlns="http://www.opengis.net/ogc" version="1.3.0" capture-installed="true">
<ServiceException code="InvalidFormat">
Output format jpg is not supported by the GetPrint request
</ServiceException>
</ServiceExceptionReport>
```
To fix this regression, it is necessary to accept JPEG output format.
And to avoid this regression to come back, the QGIS Server tests has been updated to accept jpg image test.
In QGIS Server 3.4, the WMTS API has been added in which the tile matrices are calculated except fro EPSG:3857 and EPSG:4326.
This commit adds the capability to select the tile matrices to use with the project and to configure the top-left corner and the last level of the tile matrix. In the case of EPSG:3857 and EPSG:4326, the user can only choose the last level of the tile matrices.

* [server] Fix layer order rendering when layers are in groups
Fixes#20810
* Update test images
* [server] Fix order of layers in subgroups
basically: layers in WMS is specified in a comma separated
list where leftmost layer is drawn first (it's at the bottom)
and QGIS layer order is exactly the opposite: first layer
in the TOP (topmost) is drawn last (it is at the top).
For this reason the server reverses the list before passing
it to the renderer.
* Fix order of layers in test
* Update src/server/services/wms/qgswmsrenderer.cpp
