Re: Use of GCPS in Rasterio
We added the `from_gcps` function to create a transformation matrix from gcps (see: https://github.com/mapbox/rasterio/pull/1773)
This is a good first step but now when we open a file we still need to do something like
with rasterio.open(src_path) as src_dst:
with WarpedVRT(src_dst, src_crs=src_dst.gcps, src_transform=from_gcps(src_dst.gcps)) as vrt_dst:
Question: I wonder if it will be possible to add an option (or env variable) for the `open` method to force the use of crs and transform created from gcps.
