It does this by enforcing mipmapping and minification filters, and
always autogenerates mipmaps and enforces anisotropic filtering for all
modes (if that's separately enabled).
This looks nice and flicker free in most games without any additional
tweaking, including GTA and Burnout which have long been painfully
flickery in the distance due to undersampling.
Needs a bit more testing before merge, maybe.

Before, it either flipped continuously, or forced frameskip on. This
makes it so you can still draw frames, but skip actual flips.
This is useful when games draw things only in a single frame and reuse
later. It's also useful when measuring speed improvements if you already
get 100% speed on a device.
