Revert windowing change from 93ab08e
...
This is actually needed to prevent spectral leakage from IDTFs with
small window sizes.

Fix position increment in STFT helper
...
This was what was causing the spectral leakage. It already sounded like
parts of the buffer were being cleared too early or old parts were being
reused, but I guess that makes sense now...

Don't do gain compensation in STFT helper
...
You'll likely want to add some scaling yourself anyways, so this would
just be a wasted operation since the scaling also depends on your window
function.
