Evas TGV saver: Use medium quality by default
The default quality is 80 and high quality is horribly slow,
so default to medium quality instead (it's already very slow).
If you really want to shoot yourself in the foot and use high
quality, just set quality > 95 and go make some coffee.
Also, disable dithering, it creates horrible artifacts on real
life pictures (gradients and flat surfaces especially).
