This was mainly included for debugging, but could end up being confusing
for users, as well as polluting the GL program cache with a mix of uber
and specialized shaders if the option was changed.
These vertex formats enable all attributes. Inactive attributes are set
to offset=0, and the smallest type possible. This "optimization" stops
the NV compiler from generating variants of vertex shaders.
This is a remake of https://github.com/dolphin-emu/dolphin/pull/3749
Full credit goes to phire.
Old message:
"If none of the texture registers have changed and TMEM hasn't been invalidated or changed in other ways, we can blindly reuse the old texture cache entries without rehashing.
Not only does this fix the bloom effect in Spyro: A Hero's Tail (The game abused texture cache) but it will also provide speedups for other games which use the same texture over multiple draw calls, especially when safe texture cache is in use."
Changed the pr per phire's instructions to only return the current texture(s) if none of the texture registers were changed. If any texture register was changed, fall back to the default hashing and rebuilding textures from memory.
Some code was calling more than one of these functions in a row
(in particular, FileUtil.cpp itself did it a lot...), which is
a waste since it's possible to call stat a single time and then
read all three values from the stat struct. This commit adds a
File::FileInfo class that calls stat once on construction and
then lets Exists/IsDirectory/GetSize be executed very quickly.
The performance improvement mostly matters for functions that
can be handling a lot of files, such as File::ScanDirectoryTree.
I've also done some cleanup in code that uses these functions.
For instance, some code had checks like !Exists() || !IsDirectory(),
which is functionally equivalent to !IsDirectory(), and some
code was using File::GetSize even though there was an IOFile
object that the code could call GetSize on.
This fixes the global-static fifo object causing infinite hangs in some
cases. Notably, failure to initialize a graphics backend would result in
BlockingLoop::Prepare being called but never executing Run(), leaving the
object in a bad state.
This code hadn't been touched since 2010. Nowadays, the panic alert
setting is loaded by ConfigManager and applied in UICommon.
VideoConfig has no business messing with it.
Use @Orphis's FindFFmpeg module from ppsspp:

From that commit:

> It is also able to find dynamic libraries, not just static libraries.

This removes the need for multiple texture files to store the mipmap
chain for a texture. As many mipmaps will be loaded as are present in
the DDS file, and any remaining mipmaps will fall back to the old
behavior.
This is because we re-use BlendingState for our internal drawing (e.g.
RasterFont) and for these shaders, we can't assume the presence of a
second color output.
Currently, we use the alpha channel from the EFB even if the current
format does not include an alpha channel. Now, the alpha channel is set
to 1 if the format does not have an alpha channel, as well as truncating
to 5/6 bits per channel. This matches the EFB-to-texture behavior.
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:

Fixes bug #10183 [0] introduced by 3bd184a / PR #4467 [1].
TextureCacheBase was no longer calling `entry->Load` for custom textures
since the compute shader decoding logic was added. This adds it back in.
It also slightly restructures the decoding if-group to match the one
below, which I think makes the logic more obvious.
(recommend viewing with `git diff -b` to ignore the indentation changes)
