This fixes the previous commit and adds more cases (DCT-I and DST-I).
I am holding off on defining a scale parameter for FFTs as I'd like
to use a complex value for them.
Patch attached.

Subject: [PATCH] lavu/tx: correctly use a default scale parameter for all
transform types
This fixes the previous commit and adds more cases (DCT-I and DST-I).
I am holding off on defining a scale parameter for FFTs as I'd like
to use a complex value for them.
