Merge remote-tracking branch 'remotes/giz/master' into ProposedMerge
On my system using Giz's V3 dir from drop box, I started V3, clicked on Configure Previews and added a preview.  Got an NPE at GDIControl.cs line 131.  Graphics was null.  Apparently this happened because AllocateGraphicsBuffer failed to set up backbuffer because Height was 0.  I traced this to the Data that GDIPreviewForm.cs was using in its Setup routine.  This change just stuffs some non-0 values in Data in case it come in bad.  Dunno why Data was bad, but suppose it has something to do with the gdi/d2d switch?
