System.Drawing Round-Trip PixelFormat Stability

If you follow me on twitter, you know that I am no fan of the System.Drawing namespace. It’s a rush job thinly wrapped layer on top of GDI+. A great deal is only partially implemented and there is quite a lot of undocumented behavior. Today I hope to help a bit with this problem by running some tests on System.Drawing.dll v2.0.50727 and documenting the results.
