BeatDrop will now use projectM-eval instead of ns-eel in v1.4.

BeatDrop is now working with projectM Expression Evaluation Library, but I found a bug 2 days ago about & and | operators, which it caused a different behavior and not pleasant to watch after 1 year of patch fixing all the presets (I did myself).

The binary and/or operators always return 1. Which isn't quite right.

Here is the comparison of how it actually broke:

The original one should look like this:

In the next hours, he posted some comparison screenshots about the new and old one. Here is a Pull Request about the fix: projectM-visualizer/projectm-eval#9
After the fix, I'll update the vcpkg and I'll do a commit.

Because the bitwise operators are fixed, BeatDrop is now officially integrated with projectM-eval library. Now it offers preset compilation time optimization, making it faster and preventing some frame drops on shaders. Stay tuned for version 1.4 with this new expression evaluation library. Hope you can't wait! 😉

Great to see more adoption, and good to have this bug found & fixed!
With most of the x86 assembly out of the way, I'd also suggest releasing a 64-bit build.

The only thing which may fail to compile are the CheckForMMX and CheckForSSE functions as they use assembly code, which IMO can be safely removed as all CPUs since the early 2000's support both instructions sets and BeatDrop will certainly not run on a 486 CPU anyways I guess.

In plugin.cpp, it only enabled checking for MMX

    m_bMMX = CheckForMMX();
    //m_bSSE = CheckForSSE();

So, commenting the first should work, maybe.

Just remove those checks and compile with default optimizations should be fine. Checking CPU features is only required if you'd use quite recent or specific additions like AVX-512 which only a few modern CPUs support. MMX was introduced in 1997 and SSE in 1999 and can be considered "always available".
