add GRASS vector layers from browser with map + layer name
GRASS: fixed crash when opening vector without topo
GRASS: points removed from topo in GRASS 7
GRASS: show layers non expandable
remember browser last expanded item
[composer] Use intersection rather than clip for transformed grids

Previous behaviour was to clip transformed grid lines to the visible
map extent. This caused problems if a map item had no border (a
solid line would be shown along the map extent), and also meant
that reprojected lines which crossed out of the map extent and back
in again did not have annotations or grid frame markings shown.

Also implement an improved logic for detecting the map frame side
for annotations.
[FEATURE][composer] Vertical descending direction for annotations

This change adds a new descending vertical direction mode for
map grid annotations. Previously only ascending text was
supported for vertical annotations.
[composer] Don't save hide bounding box setting between sessions

In practice the workflow is better if this setting is only
temporarily applied to a composer.
[FIXED] #11572 ilter Legend By Map Content doesn't maintain point displacement legend

For point vector layer render with 'displacement point', when 'Filter
 Legend By Map Content' is activated, the legend is not rendered even
 if it has to be.

It's due to QgsPointDisplacementRenderer that embedded the real
 renderer.

The solution proposed in this patch is to get the embedded renderer
 for QgsPointDisplacementRenderer.
