Minor change to solution. Removed CodeLab project stub, which was
still targeting .NET Framework 4.6.1.
The other projects with WPF code target 4.6.2, and I haven't updated
them to 4.8 out of a fear that it might make 6502bench harder to
install on older systems. The down side is that it requires an
extra "dev pack" download to build the source code. 4.8 is the end
of the line for .NET Framework, so at some point we should make that
the official target.
Visualization animations are now exported as animated GIFs. The
Windows stuff is a bit lame so I threw together some code that
stitches a bunch of GIFs together.
The GIF doesn't quite match the preview, because the preview scales
the individual frames, while the animated GIF uses the largest frame
as the size and is then scaled based on that. Animating frames of
differing sizes together is bound to be trouble anyway, so I'm not
sure how much to fret over this.
Doesn't work 100% correctly -- in some cases, using two different
combos in quick succession will fail -- but it's close.
Added stub methods for the four hint operations.
