e3f09525db Refactor the thumbnails generation of cels 
A new Render::renderCel() method is used to render the specific cel
thumbnail, useful in the future to render thumbnails of different kind
of layers (e.g. future tilemaps). And now the background is rendered
in a different step (so the thumbnails doesn't contain the
background.)

c690747bd2 Improve color conversion preview without clearing the old image 
It is better for continuous preview feedback to keep the old image so
the new preview result is painted above the old one (and there is no
flicker effects).

e1437a20c3 Fix Floyd-Steinberg error propagation for the 1/16 part 
This patch fixes the quantization of a complete gray
image (RGB=128,128,128), which must generate a black and white
checkered pattern when the Floyd-Steinberg filter is applied.

b6d07d995f Fix error diffusion algorithm 
The error propagation must be limited to 0...255 values, and the new
quantization error must be calculated to that limited value. Also the
1/16 part of the Floyd-Steinberg distribution must be the remaining of
the other parts.

29a4c6f744 Fix accessing to invalid Site object after undoing/redoing 
Mainly the site.layer() field of the context writer after an undo/redo
is not valid anymore (e.g. because the layer could have been removed).
Now we get the new active site (Context::activeSite()) to go to that
place after the undo/redo operation.

42d5f10437 Fix access to memory out of scope on Sprite Properties when assigning/converting color profiles 
Some buttons where calling the updateButtons() lambda that were
defined inside a sub-scope of SpritePropertiesCommand::onExecute()
(which is where the window is displayed
ui::Window::openWindowInForeground()), the lambda was already
out-of-scope when it was used by other lambdas.
