Jehan c3ef79b3ef Issue #12577: get rid of the gamma hack. 
What it was doing was casting the input buffer to another TRC, basically
pretending the data was what it was not. In particular, it was casting
linear input buffers to non-linear and all other TRCs to linear.

As was noted in #1958, this was in fact a useful trick, yet it's still a
trick. Basically when it's needed, it's either:

1. because the operation implementation does not work in the technically
   correct space. Then the operation code should be fixed;
2. or because several work TRC are valid, then an option should be
   proposed by the operation;
3. or for artistic reasons, which people are free to implement as
   plug-ins or third-party filters, but it should not be a core GIMP
   feature.

Therefore for most cases where it felt needed, the real solution will be
to improve the operations' implementations.
