Well tonemapping has allways been considered on my todo for 2.1... For
2.0 it's ldr2hdr, on the other hand, bala on irc (who also wrote a
filter which will soon be imported in svn, in krita-plugins for
starting) is willing to give a try to tonemapping.

We need to find the solution to that one, has for me the two floats
colorspaces are completed and fully functionnal (except for the profile
part for display convertion).

We need to put together the list of those things:
 - three filters : levels, halftoning and colorify
 - smudge

As for bug fixes, I forward port them straight away to avoid forgetting
them.

Any reason behind that ? (out of curiosity)

and we might want to use _mm_malloc (from mm_malloc.h) to get alligned
data for sse instructions

and until we do the convolution in two passes, vertical and horizontal,
but that's on my todo for a much later date.

Well we have more or less decided to use mask for adjustement layer in
2.0 instead of drawing on them, haven't we ?
