More work getting ready for presenting the MEGA65 at Linux Conf

We have been accepted to give a talk at Linux Conf in Christchurch New Zealand in January, and I really want the MEGA65 to be able to present itself at that event, rather than using another device to run the slides.  Many of you will have seen the recent work towards that.  We have more progress now, with basic slide editing and presentation mode working now:

You can edit slides, and switch between them, and go back and forth between editor and presenter modes (which really just changes whether the cursor is there and editing is available for now).

There are still a bunch of bugs and performance improvements (rendering the text is still much slower than it should/could be, for example), but it fundamentally works. With a little effort, it is possible to make simple presentations like this one.  And as it is built on our prior work on anti-aliased text for the MEGA65, it really looks quite nice, which is a bit clearer in the still image:

In the video you can also see sprites with alpha blending.  This is used for the slide number indicator that appears on the bottom right corner of the screen and then fades out using an alpha transition from opaque to transparent to smoothly disappear.
