## Description of change
- Adds MJPEG camera support using Media Foundation decoding.
- Moves camera capture to asynchronous Source Reader callbacks.
- Supports native NV12 and YUY2 capture, preferring target-sized native
formats over MJPEG when possible.
- Improves capture and rendering performance through callback-paced
reads, bulk frame uploads, optimized row-based flips, and lazy
allocation of flip textures.
- Makes runtime media-type changes interrupt pending reads and safely
flush and reconfigure the Source Reader.
- Improves automatic mode selection based on aspect ratio, proximity to
1280x720, frame rate, and capture format.
- Hardens camera shutdown, flush handling, media-type changes, and
repeated capture failures.
## Testing
Tested with two cameras in tdj
This was a lot more background work than expected, but that is the
nature of unnecessary hobbies I guess. Most things in here are obvious,
so here's the non-obvious thoughts and notes:
1. All the XP stuff is optional, if the toolchain isn't available it
won't even try
2. The docker build is the "known good" build and now has all the
required tools for XP and checking binaries
a. If you're OK with it, can add the XP_MUST_BUILD flag to
build_docker.sh
4. New `SPICE_XP` flag to comment out blocks
5. We could technically build using the Docker image I've made for my XP
compatible LLVM toolchain, but combining the binaries into a single zip
at the end of it is somewhat tedious, so I've chosen to grab the
binaries from my release
6. I also wrote a DLL checker to make sure the final binaries are
_actually_ XP compatible, which found some issues on x86_64 (I don't
know a single game that runs on 64 bit XP, but it wasn't too much effort
so whatever). This also won't run if missing, just to save the trouble.
7. The build script is still pretty shit, I've made some minor
improvements
a. `/usr/bin/env bash` instead of `/bin/bash` as it's more correct
b. Adding `-it` to the docker build, so Ctrl+C actually halts it
c. Main issue is that failures don't halt, because of the custom error
catching function. This has caused a lot of frustration, maybe we can
change that
## Testing
It runs on 32 and 64 bit installs of XP. My jubeat cab is on Win10 these
days and I haven't got around to testing an actual game, but I've
distributed test builds of this to people who *have* confirmed it works
as expected.

#477
## Description of change
Add a new option for scaling the overlay.
Gitadora Arena will receive 250% by default.
Various overlay windows have been updated to scale properly, not perfect
but they are at least usable.

## Description of change
When copying text to clipboard, the last character was being dropped due
to incorrect string buffer size calculation.
Also, clean up callers to just pass std:string by reference instead of
going back and forth between C-style strings.
Lastly, fix `git archive` in `build_all.sh` which broke after github
migration.
## Compiling
Yes
## Testing
Tested all three callers - IIDX cam hook, scard reader in Cards tab, and
patch manager datecode.
