Comment:

 Replying to [ticket:3150 huhabla]:
 > I would like to post a patch that enables direct region settings in
 r.out.png.

 I agree that this would come handy time to time. For example, G7:r.mapcalc
 (>=7.4) has region option to customize the region based on the inputs.
 General modifications of region, such as the one you suggest, would apply
 to many modules.

 I think this would be better addressed generally as we discussed in
 [https://lists.osgeo.org/pipermail/grass-dev/2016-September/082412.html
 Adding an expert mode to the parser] and
 [https://lists.osgeo.org/pipermail/grass-dev/2016-November/082927.html
 Passing computational region to individual commands].

 I suggest to close this as won't fix and open another ticket suggesting
 change on the library and parser level or on the level of grass.py
 covering the --exec case.

 > This patch is only useful if the current region should not be changed or
 can not be changed due to access restrictions of the mapset.

 I was also in this situation and really for outputs and rendering, even
 many GUI operations, there is no need to have any write access or
 ownership (see also #2511). The current solution for this particular use
 case and r.out.png is the GRASS_REGION environmental variable.
