Some widescreen hacks (see below) properly force anamorphic output, but
don't make the last projection in a frame 16:9, so Dolphin doesn't
display it correctly.
This changes the heuristic code to assume a frame is anamorphic based on
the total number of vertex flushes in 4:3 and 16:9 projections that
frame. It also adds a bit of "aspect ratio inertia" by making it harder
to switch aspect ratios, which takes care of aspect ratio flickering
that some games / widescreen hacks would be susceptible with the new
logic.
I've tested this on SSX Tricky's native anamorphic support, Tom Clancy's
Splinter Cell (it stayed in 4:3 the whole time), and on the following
widescreen hacks for which the heuristic doesn't currently work:

Approximately three or four times now, the issue of pointers being
in an inconsistent state been an issue in the video backend renderers
with regards to tripping up other developers.
Global (ugh) resources are put into a unique_ptr and will always have a
well-defined state of being - null or not null
This drops the "feature" to load level 0 from the custom texture
and all other levels from the native one if the size matches.
But in my opinion, when a custom texture only provide one level,
no more should be used at all.
A number of games make an EFB copy in I4/I8 format, then use it as a
texture in C4/C8 format. Detect when this happens, and decode the copy on
the GPU using the specified palette.
This has a few advantages: it allows using EFB2Tex for a few more games,
it, it preserves the resolution of scaled EFB copies, and it's probably a
bit faster.
D3D only at the moment, but porting to OpenGL should be straightforward..
