I was going to ask if the 20.0 library was 20.1-safe but thought it unlikely at alpha 1 stage.

So I did my usual speculative creation of a graphics.20.1.sws to see if my 390 20.0 sources would all compile and about 30 have issues with graphics package errors in gdi.h. Pretty good hit rate, I'm happy enough with that, I haven't really gone beyond the features of 3.04 yet.

More bits from the library are now in the 20.1 product Wingdi.pkg, though I haven't checked all the err files.
