Couldn't this be changed so that the *C* versions are stored in
typo3temp/RTEmagicC like any other rendered images that we are able to
recreate from the source/original (e.g. with GIFBUILDER or as a resize)?

I think we could:

P: RTEmagicP_a3_01.tif
C: RTEmagicC_a3_01.tif.jpg

and

P: RTEmagicP_a3_01.jpg
C: RTEmagicC_a3_01.jpg

The function to calculate P from C is still reversible, we just have to
skip the dropping of the extension in case there is just one.

But I agree we should leave it as is, because this is only cosmetical
and changing it won't give us much.
