RGB 16 bit as default when starting Krita

[Dmitry Kazakov]

I'm against both. Against as default.

1) I don't know how about painting, but in photography 16bit makes
absolutely nothing. Well, yes, you can invent a couple of testcases with
"just-converted-from-raw" files, but the result will be extremely subtle. It
surely does not worth doubled memory/cpu consumption.
There are HDR's but:
  a) they are not default choice for Krita
  b) after temporary merge in 16bit done, nevertheless they should be
converted to 8bit

2) What are you speaking about, guys!? That is a completely theoretical
colorspace! It has nothing common with real life! There is hardly present a
monitor covering AdobeRGB, not speaking about this stuff.
Yes, this is really funny to scale a dalai lama picture, but it'll create
an enormous amount of problems to our users working with real-world images.

PS:
I'm not even speak about the problems our users face, when they decide to
print their masterpiece in the lab..
