9dab2db33b Avoid copying the convolution filter history to shift it 
Instead, the current/head/newest segment is tracked, and decremented with each
process to overwrite the oldest.

801c7a9226 Initial implementation of the convolution effect 
Currently limited to mono and stereo impulse responses, and stereo IRs try to
use direct/real output rather than panning.

48fbad9836 Slightly improve the Hann windows 
There's no need to include the 0 terms on the ends since they'll never
contribute a sample. So extend the width to have the 0 terms just outside the
window where it wouldn't contribute anyway.

93e677edb3 Precalculate some values 
MSVC isn't as willing to precompute sqrt and log10 results from known input
values.

ab6afd6fa0 Reimplement the modulation stage for reverb 
This seems to be quite close recordings from real hardware, so it's probably
good enough.

c5f88ab59f EFX: Add explicit cast to a square function 
MSVC 2015 and above returns the expression according to its datatype.
In this case, returns 4294967295 instead of -1.

1bb93f4fc2 Avoid direct function template and alias types 
It's somewhat ambiguous what they mean. Sometimes acting as a pointer, other
times having weird behavior. Pointer-to-function types are explicitly defined
as such, whereas uses of these tend to be as references (never null and not
changeable).

5f6a35c960 Avoid storing an integer in a pointer 
C++ does not guarantee that, given an int of sufficient size, converting
int->ptr->int will result in the original value. A pointer may have more than
one integer representation. Only ptr->int->ptr round trips are well-defined.
