Description
If I am loading a shapefile on a Sentinel-1 cube the shapefile is shifted by a few pixels because the size of outmat in rasterize and the length of the bounding box doesn't coincide.
I have to fill this with clearer data, but I wanted to report this now, so that we don't forget it.

Research direction
Start at cubefromshape and its rasterize path, comparing the size of outmat with the bounding-box length on a Sentinel-1 cube. Reproduce the issue with clearer shapefile and cube data, then verify that the rasterized shape is no longer shifted by a few pixels.
