gfx_candyflow crash on macOS.

[vifino]

When run on macOS, it complains about the lack of the symbol _perf_start.

Error:

@orithena If you could have a look at why that happens, I'd appreciate it.

gfx_affinematrix also has this problem.

I fixed that with lost symbol by marking it static: As it's simply included then, this is fine.

However, now it complains about another missing symbol..

Unsurprisingly, it was the same issue of function being defined in a header, with another static it's fixed. I'll push it.

[vifino]

Oh, you already fixed it, thanks @orithena!

@vifino: Yeah, it came up on linux when compiling with -O0 to get a full backtrace for #35 without variables being optimized out ^^

[vifino]

Ah, excellent, so it wasn't just macOS being weird, great!
