This commit sets a different way of handling SAGA versions and a new way of checking saga installations
This is done to fix the messy situation that SAGA causes due to its API changing in each release.
* Delete r.bitpattern.txt: r.bitpattern is now only an Addon since r.mapcalc and i.modis.qc provide the functionality
* r.describe.txt: flag description cosmetics
* r.random.raster.txt: fix typo
* Update and rename r.shaded.relief.txt to r.relief.txt (http://trac.osgeo.org/grass/wiki/Grass7/NewFeatures#Renamedmodules)
* Update r.sunmask.txt: -s added but "Outputraster" needs to be optional for that [TODO]
* Update r.surf.area.txt: "units" added
* Delete r.surf.idw2.txt: r.surf.idw2 is now a GRASS GIS Addon (http://trac.osgeo.org/grass/wiki/Grass7/NewFeatures#Replacedandremovedmodules)
* Delete v.transform.pointsfile.txt: The pointsfile parameter no longer exists. Use v.transform.txt instead
* Update TODO
When layer set is locked in composer map, also the styles associated with layers are kept.
As a result, a composition can contain maps of the same layer just with different styles.
Map settings and map renderer jobs have been improved to support temporary override of layer's style.
It is possible to pass to map settings which layers should have overridden style and map jobs
will temporarily replace the style (just for the rendering).
- style manager is always enabled (client code does not need to distinguish between enabled/disabled state)
- layers currently active style is stored only in QgsMapLayer - in style manager it has entry with no data (avoids duplication of data)
This also solves issues with visibility presets and styles when some presets do not have stored style
QgsOptionsDialogBase was incorrectly finding the projection
selector's buttonBox widget and attaching the connections
to that widget, rather than the dialog's widget.
Rename projection selector's button box to avoid this conflict.
[FEATURE] Support for multiple styles per map layer
Available in legend context menu in Styles sub-menu where it is possible to add/remove styles
and quickly switch between them.
