So probably not my VIA Unichrome chip then :-( (I wish I had some proper documentation for it. The best that I have been able to find is the source code for the various drivers, which are poorly commented, and only set a lower bound on what the hardware is able to do. For example I noticed a set of #defines in a header file that may have been defining different types of interpolation for stretch-blits, which could be very useful, but I can only guess how to use them....)
