The problem with VS2012 is that there was no free SKU that could be used for 
driver dev. VS2013 has also gone out of support (on 09/04/2019). Both vs2012 
and vs2013 scripts are still there in staging-8.2 and I have no intention to 
remove them from there, but I'd really rather not have them in master as 
maintaining multiple sets of vcxproj files is annoying and dealing with both 
2015 and 2017 is bad enough.
