add option to draw value as boxes, not lines (currently only with qwt6 and Byte data)
let the raster provider/interface calculate histogram bin count, and make sure there are no more bins than actual range (max-min) for Int16/32 bands
draw histogram boxes for Int16/Int32 also
add HistogramItem from qwt5 examples for use by histogram widget
implement updateLegend() in HistogramItem
allow to plot histogram as boxes with qwt5, using HistogramItem
change histogram bar outline color from black to lightGray
disable 'Draw as lines' option when raster layer does not contain int bands'
disable raster histogram test until rendering testing is improved (also this test depends on qwt version 5 vs. 6)
add files for raster histogram (Int16 and Float32)
add grass r.cost module with no need for stop points input
[BUGFIX] 9234 - WFS client doesn't expose Header Authorization

Like for the others OGC providers: WMS and WCS, the user can set the
login and password to access to WFS protected data. But the QGIS WFS
provider doen't expose header authorization. It doesn't use login and
password.

This patch set header authorization for all WFS connexion if login and
password are set.
And I think this patch has to be backported to release_2-2, because QGIS
can't acces to protected WFS data.
Make QgsComposer window WindowModal
Adjust the arrow points to fit inside the specified bounding
 box, as opposed to adjusting the bounding box for the arrow points (except
 when bounding box is too small)
Ask whether to save existing project when creating a new
 project from a template.
