[QGIS-Developer] Proj 7 auto grid download

[Andreas Neumann]

Hi, Jürgen,

Thanks for explaining the situation. 500MB is definitely too large and 
it would be useless data for most users.

Might it be an option to store grid-shift files alternatively also in 
the QGIS user directory - I mean the folder where the user stores his 
settings, plugins, expressions. I agree that many users wouldn't have 
access to the main install directory.

Alternatively, would it be possible to integrate an additional 
step/choice in the standalone installer that would download grid-shift 
files of interest for the user?

Thanks,

Andreas
